hw-module profile load-balance algorithm

To enable the load-balancing mode for PPPoE traffic in the router, use the hw-module profile load-balance algorithm command in the Global Configuration mode.

hw-module profile load-balance algorithm { L3-only | PPPoE | gtp | gtp-mpls | inner-l2-field | ip-tunnel | layer2 | mpls-lsr-ler | mpls-lsr-ler-optimized | mpls-safe-speculative-parsing }

Syntax Description

ip-tunnel

Allows the hashing algorithm to use the outer IPv4 GRE header even while doing an IP tunnel decapsulation.
layer2

Allows the hashing algorithm to use the inner IP header information while doing layer 2 forwarding with inner payload as MPLS.
gtp

Allows hashing based on the tunnel id in GTP-U packets.

gtp-mpls

Allows hashing based on the tunnel id in GTP-U packets intead of Layer 4 packets when underlay network is MPLS.
mpls-safe-speculative-parsing

Allows hashing based on the first nibble of the MAC DA address.

pppoe

Allows hashing based on inner IPv4 or IPv6 headers for PPPoE packets to perform the traffic load-balancing. We recommend enabling this hashing on head and tail nodes.

L3-Only

Allows hashing for L3 header only. We recommend enabling this hashing when majority of traffic is fragmented.

mpls-lsr-ler

Allows hashing in Label Edge Router (LER) and Label Switched Routers (LSRs) with MPLS traffic.

This profile is recommended to be used when the following traffic flows are prominent:

  • IPv4 pop and lookup flows (EthoMPLS2/3oIPv4oL4) with L4 as TCP or UDP

  • IPv6 pop and lookup flows (EthoMPLS2/3oIPv6oXX) with L4 as TCP or UDP

mpls-lsr-ler-optimized

Allows optimized hashing in LER and LSR with MPLS IPv6 traffic.

This profile is recommended to be used when the following traffic flows are prominent:

  • 4 Label IPv6 flows (EthoMPLS4/6oIPv6)

  • IPv6 pop and lookup flows (EthoMPLS2/3oIPv6oXX) with L4 as non-TCP/UDP (for example, no next header, GRE)
inner-L2-field

Allows the hashing algorithm to use the inner ethernet fields of the source MAC and destination MAC addresses.

Command Default

The load-balancing mode is disabled by default.

Command Modes

Global Configuration mode

Command History

Release

Modification

Release 7.4.1

This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Without control-word, L2VPN traffic is considered to be IPv4 or IPv6 traffic depending on the presence of nibble 4 or nibble 6 in the payload after the last label in the traffic. The matching offset fields are considered for load-balancing hash calculation. This may cause hashing of a single flow to different links resulting in decrease of end user throughput.

While adding or removing these commands, you must reload the router.

  • hw-module profile load-balance algorithm ip-tunnel

  • hw-module profile load-balance algorithm PPPoE

The hw-module profile segment-routing srv6 is mutually exclusive with hw-module profile load-balance algorithm PPPoE and hw-module profile load-balance algorithm ip-tunnel commands.

Command Description

show l2vpn

Displays L2VPN information  

show l2vpn bridge-domain (VPLS)

To display information for the bridge ports such as attachment circuits and pseudowires for the specific bridge domains, use the show l2vpn bridge-domain command in XR EXEC mode.

show l2vpn bridge-domain [autodiscovery | bd-name bridge-domain-name | brief | detail | group bridge-domain-group-name | hardware | interface type interface-path-id | pw-id value ] neighbor IP-address [pw-id value | pbb | summary]

Syntax Description

autodiscovery

(Optional) Displays BGP autodiscovery information.

bd-name bridge-domain-name

(Optional) Displays filter information on the bridge-domain-name . The bridge-domain-name argument is used to name a bridge domain.

brief

(Optional) Displays brief information about the bridges.

detail

(Optional) Displays detailed information about the bridges. Also, displays the output for the Layer 2 VPN (L2VPN) to indicate whether or not the MAC withdrawal feature is enabled and the number of MAC withdrawal messages that are sent or received from the pseudowire.

group bridge-domain- group-name

(Optional) Displays filter information on the bridge-domain group name. The bridge-domain-group-name argument is used to name the bridge domain group.

hardware

(Optional) Displays hardware information.

interface type interface-path-id

(Optional) Displays the filter information for the interface on the bridge domain.

Note

 

Use the show interfaces command to see a list of all interfaces currently configured on the router.

For more information about the syntax for the router, use the question mark (? ) online help function.

neighbor ip-address

(Optional) Displays the bridge domains that contain the pseudowires to match the filter for the neighbor. The ip-address argument is used to specify IP address of the neighbor.

pw-id value

(Optional) Displays the filter for the pseudowire ID. The range is from 1 to 4294967295.

pbb

(Optional) Displays provider backbone bridge information.

summary

(Optional) Displays the summary information for the bridge domain.

Command Default

Command History

Release Modification

Usage Guidelines

Use the interface keyword to display only the bridge domain that contains the specified interface as an attachment circuit. In the sample output, only the attachment circuit matches the filter that is displayed. No pseudowires are displayed.

When an SR policy is configured as the preferred path for a VPLS circuit, the traffic traverses through the SR policy path. The PW counters are updated with statistics about packets transmitted and received. When the SR policy configuration is deleted, the traffic session is still functional because the traffic transmission switches back to the normal LSP path between the PEs. There is no drop in the end-to-end traffic transmitted. However, the packet statistics counters are reset and start from zero. This is because, when the SR policy is deleted, the PW too gets deleted and the statistics information associated with the old PW is cleared. The counter restarts from zero when the new PW is created after the switch takes place.

storm-control

To enable storm control on an access circuit (AC) under a VPLS bridge, use the storm-control command in l2vpn bridge group bridge-domain access circuit configuration mode. To disable storm control, use the no form of this command.

storm-control {broadcast | multicast | unknown-unicast} { pps pps-value | kbps kbps-value}

no storm-control {broadcast | multicast | unknown-unicast} { pps pps-value | kbps kbps-value}

Syntax Description

broadcast

Configures storm control for broadcast traffic.

multicast

Configures storm control for multicast traffic.

unknown-unicast

Configures storm control for unknown unicast traffic.

  • Storm control does not apply to bridge protocol data unit (BPDU) packets. All BPDU packets are processed as if traffic storm control is not configured.

  • Storm control does not apply to internal communication and control packets, route updates, SNMP management traffic, Telnet sessions, or any other packets addressed to the router.

pps pps-value

Configures the packets-per-second (pps) storm control threshold for the specified traffic type. Valid values range from 1 to 160000.

kbps kbps-value

Configures the storm control in kilo bits per second (kbps). The range is from 64 to 1280000.

Command Default

Storm control is disabled by default.

Command Modes

l2vpn bridge group bridge-domain access circuit configuration

Command History

Release

Modification

Release 6.3.1

This command was introduced.

Usage Guidelines

  • The storm control configuration is supported only on one sub-interface under a main interface, though the system allows you to configure storm control on more than one sub-interface. However, only the first storm control configuration under a main interface takes effect, though the running configuration shows all the storm control configurations that are committed. After reload, any of the storm control configurations may take effect irrespective of the order of configuration.

  • Starting from 7.8.1, you can enable per subinterface configuration support for storm control by using the hw-module storm-control-combine-policer-bw enable command.

  • System supports storm control per-EFP.

  • If storm control is applied on one bridge port, you cannot apply storm control on another bridge port or sub-interface under the same main-port. On configuring, system pop-ups an error, but needs to be manually unconfigured.

  • System does not support storm control on pseudowire bridge-ports.

  • Storm control counters are not supported

  • Only kbps rate is supported by hardware. Though the pps configuration is allowed, it is converted to kbps. The pps rate is calculated as 1 pps = 8 kbps.
