configure vlan esrp esrp-election
ExtremeWare 7.7 Command Reference Guide 1543
The
ports-track-priority
or
track-ports-priority
options can be used to ensure that there is no
failback if the original Master recovers (the Master will have the same ports, tracks and priority, but a
higher MAC).
If a switch is master, it actively provides layer 3 routing services to other VLANs, and layer 2 switching
between all the ports of that VLAN. Additionally, the switch exchanges ESRP packets with other
switches that are in slave mode.
If a switch is in slave mode, it exchanges ESRP packets with other switches on that same VLAN. When
a switch is in slave mode, it does not perform layer 3 routing or layer 2 switching services for the
VLAN.
Example
The following command configures the election algorithm to use tracking information as the first
criteria for determining the ESRP master switch for VLAN
esrp-1
:
configure vlan esrp-1 esrp esrp-election track-ports-priority-mac
