Dynamic Bonding Group for RPHY

The Dynamic Bonding Group (DBG) feature enables the system to automatically create bonding groups of different sizes based on the cable modems’ capacity. It helps to manage the resources of all downstream bonding groups. When the number of available bonding groups reaches the lower limit, it reclaims the bonding groups that match the reclaim threshold set by the user. The modems used on these bonding groups are then moved to other bonding groups without primary channel change. This move makes space for new bonding group allocations. This automated way of creating and reclaiming bonding groups greatly reduces the management effort of RCC configuration. DBG also automatically accommodates primary channel and CM capacity distributions.

The load balancing feature leverages DBG to balance traffic among all channels. With DBG, the modem is assigned to the downstream bonding group without any static RCC configuration.

DBG supports the following:

  • DOCSIS 3.0 and DOCSIS 3.1 channel types.

  • DOCSIS 3.0 and DOCSIS 3.1 load balance.

  • Interoperation with modem registration, load balancing, and high availability.

  • Enhanced dynamic load balance to allow movement of modem without a change in the primary channel.

  • Enhanced FPGA to allow channel utilization fairness.

This chapter describes how to configure the DBG feature on the Cisco Remote PHY Device.

Configure Dynamic Bonding Group

Before configuring DBG, it is assumed that interface Mac domain and fiber node are already configured on the Cisco cbr-8 router. The recommended primary channel distribution is one primary channel for contiguous four channels, such as 0, 4, 8, 12, 16, 20, 24, 28 and so on. For more information, see DOCSIS Interface and Fiber Node Configuration in the Cisco cBR Converged Broadband Routers DOCSIS Software Configuration Guide.

Enable Dynamic Bonding Group

DBG is disabled by default. Use cable dynamic-bonding-group command to enable DBG as shown in the following example: 


ROUTER# configure terminal
ROUTER(config)# cable dynamic-bonding-group
ROUTER(config)# end

To configure the bonding group reclaim threshold, use cable dynamic-bonding-group reclaim-threshold command as shown in the following example: 


ROUTER# configure terminal
ROUTER(config)# cable dynamic-bonding-group reclaim-threshold percent 5% modems 6
ROUTER(config)# end

5% is the default bonding group throughput percentage threshold, and 6 is the default cable modem count threshold. If the throughput of a bonding group is lower than 5% of all bonding groups’ throughput, and this bonding group has less than 6 cable modems assigned to it, then this bonding group is reclaimed when the available bonding groups reach the lower limit (20%).

By default, cable modem registration and load balance trigger DBG creation when needed. If you want to disable the interoperation with cable modem registration and load balance, use the commands in the following example: 


ROUTER# configure terminal
ROUTER(config)# no cable dynamic-bonding-group registration

ROUTER# configure terminal
ROUTER(config)# no cable dynamic-bonding-group load-balance

When DBG is enabled, we recommend you to complete the following configurations.

Enable DS-Resiliency and Configure Resiliency Bonding Group

To make sure that the modem is still in w-online state with maximum downstream capability when several RF channels are impaired, enable the ds-resiliency feature by running the following commands: 


Router# configure terminal
Router(config)# cable resiliency ds-bonding
Router(config)# end


Router# configure terminal
Router(config)# interface wideband-Cable 3/0/1:30
Router(config-if)# cable ds-resiliency
Wideband-Cable3/0/1:30 is set to WB resiliency bonding group.
Remove any existing bundle and rf-channel configuration.
Router(config-if)# end

Enable ACFE

Enable ACFE feature to make sure that modem registration is not blocked because of QoS failures:


Router# configure terminal
Router(config)# cable acfe enable
Router(config)# end

Verify Dynamic Bonding Group Configuration

This section describes how to use certain show commands to verify if the dynamic bonding groups are created.

Check the modem’s primary wideband interface using the show cable modem wideband channel command as shown in this example: 


Router# show cable modem 4800.33ee.ebee wideband channel

Table 2. Dynamic Bonding Group States

DBG State

Description

CREATE_WAITING_SUP

Line card sends a request to create DBG and waits for SUP to create the bonding group.

HOLD

DBG is created from SUP, or bonding group reverts from reclaim to ready-for-use state.

OPERATIONAL

If a modem is used on the bonding group after the HOLD state times out, the DBG state changes to OPERATIONAL.

RECLAIM_HOLD

Ready for reclaim.

If no modem is used on the bonding group or match the reclaim in two minutes, the bonding group is reclaimed. The DBG state changes to RECLAIM_HOLD.

RECLAIM_MODEM_MOVING

Ready for reclaim.

The modem is moved out of the bonding group.

RECLAIM_WAITING_SUP

Line card sends a DBG reclaim request and waits for SUP to reclaim the BG.

To display the detailed channel list information of dynamic bonding group, use the show derived-config interface wideband command as shown in the following example: 


Router# show derived-config interface wideband-Cable 3/0/1:1
Building configuration...
Derived configuration: 113 bytes
!
interface Wideband-Cable3/0/1:1
  cable bundle 255
  cable rf-channels channel-list 0-7 bandwidth-percent 1
end

Check the usage of bonding group resource using the show cable dynamic-bonding-group quota command. 

Router# show cable dynamic-bonding-group quota controller 3/0/1
slot/subslot/ctrlr: 3/0/1
Total BG number: 128
Used BG number (static/dynamic): 6(1/5) Available BG number: 122
Available BG list port: 0, 6-29, 31-127

Check the reclaimed bonding group using the show cable dynamic-bonding-group reclaim-history summary command:

Configure Load Balancing with Dynamic Bonding Group Enabled

If you want to use load balancing with the DBG enabled, we recommend that you configure the load balancing as shown here.

Enable Load Balancing for DOCSIS 3.0 and DOCSIS 3.1

To enable DOCSIS load balancing, run the following commands:


Router# config terminal
Router(config)# cable load-balance docsis-enable
Router(config)# end

When DOCSIS load balancing is enabled, run the following commands to enable load balancing for DOCSIS 3.0 and DOCSIS 3.1.


Router# config terminal
Router(config)# cable load-balance docsis30-enable
Router(config)# end

Enable DOCSIS 3.0 and DOCSIS 3.1 Static Load Balance

To balance the load of primary channels, enable static load balance using the following commands:


Router# configure terminal
Router(config)# cable load-balance docsis30-enable static
Router(config)# end

Enable DOCSIS 3.0 and DOCSIS 3.1 General Load Balance Group

To enable general load balance group, use cable load-balance docsis-group command as shown here:


Router# configure terminal
Router(config)# cable load-balance docsis-group fn 1 md c3/0/1
Router(config-lb-group)# no disable
Router(config-lb-group)# end

Enable Dynamic Load Balance and Fixed-Primary Channel Movement

To balance the load of all downstream channels based on utilization, enable dynamic load balance by running the following commands: 


Router# configure terminal
Router(config)# cable load-balance docsis30-enable dynamic downstream
Router(config)# end

Fixed primary channel movement is disabled by default. With dynamic load balancing enabled, we recommend that you enable fixed primary channel movement to reduce service outage by running the following commands: 


Router# configure terminal
Router(config)# cable load-balance fixed-primary-channel
Router(config)# end

Verify Static Load Balancing Configuration

This section describes how to use show commands to verify the configuration of the static load balancing.

Check the load of all primary channels using the show cable load-balance docsis-group load command as shown here: 


Router# show cable load-balance docsis-group fn 1 md c3/0/1 load | in In
Interface           State   Group      Utilization Rsvd NBCM WB/UB Weight

In3/0/1:16(669 MHz) initial 2147557888 0%(0%/0%)   0%   0    13    37
In3/0/1:20(693 MHz) initial 2147557888 0%(0%/0%)   0%   0    13    37
In3/0/1:24(717 MHz) initial 2147557888 0%(0%/0%)   0%   0    13    37
In3/0/1:28(741 MHz) initial 2147557888 0%(0%/0%)   0%   0    13    37

This command output lists all primary channels and shows the number of cable modems used with these channels. NBCM is the number of narrowband modems used with a channel while WBCM (WB/UB) is the number of wideband modems used with a channel. The total number of WBCMs must be balanced among all channels.

The difference between the total number of WBCMs used with any two channels is smaller or equal to the minimum threshold load. The default value of the minimum threshold load is 5.

This example shows the load in DOCSIS 3.1 static load balancing configuration:


Router# show cable load-balance docsis-group fn 33 md c3/0/0 load | i In
Interface           State    Group      Utilization Rsvd NBCM WB/UB Weight 
In3/0/0:0(453 MHz)  initial  2147557408 1%(0%/1%)   0%   0    16    37 
In3/0/0:8(501 MHz)  initial  2147557408 1%(0%/1%)   0%   0    16    37 
In3/0/0:30(633 MHz) initial  2147557408 1%(0%/1%)   0%   0    12    37 
In3/0/0:40(693 MHz) initial  2147557408 1%(0%/1%)   0%   0    15    37 
In3/0/0:55(783 MHz) initial  2147557408 1%(0%/1%)   0%   0    12    37 
In3/0/0:158(258 MHz initial  2147557408 1%(0%/1%)   0%   0    21    224 

   - Above example, the modem count balanced with a configured threshold of 5

   - Count based load balancing is done only on sc-qam channels of equal weight. OFDM channel is of much higher weight and is excluded from the modem count calculations.

Check the load of all RF channels using the show cable load-balance docsis-group rfch-util command as shown in this example: 

Router# show cable load-balance docsis-group fn 1 md c3/0/1 rfch-util

LB_CM_DYANMIC_MOVING

Modem is in movement triggered by dynamic load balance.

LB_CM_DISABLED

Modem is not ready for movement. If the modem failure movement count reaches maximum failure threshold, then set the modem in LB_CM_DISABLED to avoid further movement.

Verify Dynamic Load Balancing Configuration

This section describes how to use the show commands to verify the configuration of the dynamic load balancing.

Check the utilization of all RF channels using show cable load-balance docsis-group rfch-util command as shown in this example:

The traffic among all RF channels is considered balanced when the difference between any two RF channel utilization is under the threshold load. The default percentage of threshold load is 10%.

To check the potential target bonding group for each of the source bonding group, use the show cable load-balance docsis-group target dbg and the show cable load-balance docsis-group target wide commands as shown in this example:

If there is no target bonding group in the output, it means that no bonding groups are created to balance traffic among RF channels.

A sample output for DOCSIS 3.1 modems with a configured threshold of 14% is shown. For utilization based load balancing to start on DOCSIS 3.1 modems, the OFDM channel must be utilized 100% and SC-QAM must have traffic. The utilization-based load balancing balances the traffic on the SC-QAM channels in a DOCSIS 3.1 modem.
