Clarifications, Known Behaviors, and Resolved Issues
VRRP
The show tech-support Command Through Telnet
In a configuration with more than 20 VLANs, if you use the show tech-support command on the
backup switch through a telnet connection, the backup transitions to master and back. To avoid this, use
the
show tech-support command only through a direct console connection (PD2-128764506).
Increase Advertisement Interval When CPU is Busy
An extremely busy CPU can create a short dual master situation. To avoid this, increase the
advertisement interval (PD2-130779223).
Backup Transition Creates Duplicate Packets
A VRRP transition from backup to master might cause duplicate packets to be transmitted for a short
period of time (PD2-129379226).
Changing the Advertisement Interval
If you configure a new advertisement interval and then reconfigure the interval back to the default,
VRRP elects a new master but keeps the existing master, resulting in two master VRRP VLANs. To
avoid this, disable and re-enable VRRP (PD2-127681301).
Changing the Priority
If you configure the VRRP master priority to 0 (releasing it as the virtual router) and then configure the
priority to 255, the master is not released even though a new master is elected. This results in two VRRP
masters. To avoid this, disable and re-enable VRRP (PD2-127681312).
The track-diagnostic and track-environment Features Not Supported
The track-diagnostic and track-environment features are not currently supported with VRRP
(PD2-127681344).
IP Unicast Routing
Deleting a Static Entry Using SNMP
If you delete a static IPARP entry using SNMP, the line in the configuration creating that entry is not
deleted. Thus, if you reboot, the static entry is again created. To work around this, either edit the
configuration or delete static IPARP entries through a direct connection to the switch (PD2-130505418).
The show iproute Output
The output of the show iproute command displays only the first 8 characters of the VLAN name
(PD2-128392829).
