ExtremeWare 7.7 Command Reference Guide 1523
configure vlan add track-ping
configure vlan <vlan name> add track-ping <ip address> frequency <seconds>
miss <number>
Description
Configures an ESRP-enabled VLAN or VRRP VLAN to track an external gateway using ping.
Syntax Description
Default
No ping tracking. Default miss number for VRRP is 3 consecutive missed ping responses.
Usage Guidelines
If the external gateway is not reachable as indicated by consecutive ping failures, the device
automatically relinquishes master status and remains in slave mode (for ESRP) or backup mode (for
VRRP).
This command can be used with both ESRP-enabled VLANs and VRRP VLANs.
Example
The following command enables ping tracking for the external gateway at 10.207.29.17, pinging every 10
seconds, and considering the gateway to be unreachable if no response is received to 5 consecutive
pings:
configure vlan esrp-1 add track-ping 10.207.29.17 frequency 10 miss 5
