Configuring Rtr - Avaya G250 Administration

Configuring RTR

For each remote device whose state you wish to monitor:
1. Use the rtr command, followed by a number from 1 to 30, to create the RTR.
G350-001(config)# rtr 5
G350-001(config-rtr 5)#
2. Use the type command to specify the remote device by address, and specify the probing
method to be employed by the RTR probe: ICMP Echo or TCP connection.
If you specify a TCP Connection operation, specify also which port to probe in the remote
device.
G350-001(config-rtr 5)# type echo protocol ipIcmpEcho 10.0.0.1
G350-001(config-rtr icmp 5)#
Or
G350-001(config-rtr 5)# type tcpConnect dest-ipaddr 147.42.11.1 dest-port
80
G350-001(config-rtr tcp 5)#
3. Optionally, use the frequency command to specify the frequency at which RTR probes
are sent. If you do not configure this parameter, the default value of 5 seconds is used.
G350-001(config-rtr icmp 5)# frequency 2 seconds
Done!
4. Optionally, use the dscp command to set the DSCP value in the IP header of the probe
packet, thus setting the packets' priority. If you do not configure this parameter, the default
value of 48 is used.
G350-001(config-rtr icmp 5)# dscp 43
Done!
5. Optionally, use the next-hop command to specify the next-hop for the RTR probe, and
bypass normal routing. The next-hop command is disabled by default.
Use the next-hop command when the G250/G350 is connected to a remote device via
more than one interface, and you wish to monitor the state of one specific interface. When
you specify the next-hop as the interface you wish to monitor, you ensure that the RTR will
probe that interface.
If the interface is an Ethernet interface (FastEthernet not running PPPoE) or VLAN
interface, specify also the interface's MAC address.
G350-001(config-rtr icmp 5)# next-hop interface FastEthernet 10/2
mac-address 00:01:02:03:04:05
Done!
