Configuring R2CP

After configuring the interfaces and verifying connectivity as described in “Configuring the Interfaces,” the next step is configuring the protocols for those interfaces.

Note R2CP is not available on the Cisco 5921 ESR.

Prerequisite Reading

Read the following chapters before selecting the appropriate protocol per interface:

Note See Appendix A, “Command Reference” for detailed command reference.

R2CP Configuration

This chapter provides the following major sections for initiating, verifying, and managing all aspects of R2CP on an interface:

Verifying R2CP Configuration

The following procedures are available for verifying the R2CP configuration on the router:

Note You can show general details related to Fast Ethernet, VLAN, and output modifiers for all R2CP clients.

Example

General R2CP Client Details

The following example shows how to display general radio client details:

Router> show r2cp clients ?
FastEthernet FastEthernet IEEE 802.3
Vlan Vlan IEEE 802.1q
| Output modifiers
<cr>

Displaying Radio Clients on an R2CP Interface

You show radio clients to exchange metric information with the radio for either all radio clients on all interfaces or for one radio client on a specific interface.

Examples

All Radio Clients on all Interfaces

The following example shows how to display all radio clients on all interfaces:

Router> show r2cp clients
R2CP Clients for all interfaces:
 
R2CP Clients for Interface FastEthernet0/1
R2CP Server IP=12.12.12.101:28672 Sock=1
 
R2CP Client ID=1 IP=12.12.12.7:5500
node heartbeat missed count=0
node heartbeat interval=5 seconds
node heartbeat missed threshold=3
node terminate ack missed count=0
node terminate ack timeout=1000 milliseconds
node terminate ack missed threshold=3
session activity timeout=1 minutes
session terminate ack timeout=1000 milliseconds
session terminate ack missed threshold=3
No Virtual Template defined.

One Radio Client on a Specific Interface

The following example shows how to display one radio client on a specific interface:

Router> show r2cp fastEthernet 0/1
r2cp clients fastEthernet 0/1
 
R2CP Clients for Interface FastEthernet0/1
R2CP Server IP=12.12.12.101:28672 Sock=1
 
R2CP Client ID=1 IP=12.12.12.7:5500
node heartbeat missed count=0
node heartbeat interval=5 seconds
node heartbeat missed threshold=3
node terminate ack missed count=0
node terminate ack timeout=1000 milliseconds
node terminate ack missed threshold=3
session activity timeout=1 minutes
session terminate ack timeout=1000 milliseconds
session terminate ack missed threshold=3
No Virtual Template defined.

Displaying R2CP Router Configuration

You can display router configuration information details for the R2CP interface. These configuration details include the following components:

  • Heartbeat threshold
  • Node-terminate acknowledgement (ACK) threshold
  • Node-terminate ACK timeout
  • Port number
  • Session-activity timeout
  • Session-terminate ACK threshold
  • Session-terminate ACK timeout
  • Virtual-access template number

Example

Displaying R2CP Router Configuration

The following example shows how to display configuration details for the R2CP interface:

Router> show r2cp config
R2CP Configuration from FastEthernet0/1
 
R2CP Server IP=12.12.12.101:28672
node heartbeat missed threshold=3
node terminate ack timeout=2200 milliseconds
node terminate ack missed threshold=2
session activity timeout=3 minutes
session terminate ack timeout=1000 milliseconds
session terminate ack missed threshold=5
virtual template=220

Displaying Neighbors on an R2CP Interface

You show neighbors on an R2CP interface to display information about the neighbors with which the radio can talk from a Layer 3, next-hop perspective. Show R2CP neighbors allows you to get metric data associated with a next-hop, so you can better understand the paths that the traffic is taking.

Example

Displaying Two Radio Neighbors/Sessions

This example shows how to display a configuration that includes two radio neighbors/sessions:

Router> show r2cp neighbors
 
R2CP Neighbors for all interfaces:
 
R2CP Neighbors for Interface FastEthernet0/1
R2CP Server IP=12.12.12.101:28672 Sock=1
