ESRP
ESRP Master Does Not Change to the Neutral State
The ESRP Master might not change to the neutral state on the super-VLAN, even though there are no
active ports on any of the sub-VLANs.
Workaround. Disable the ESRP on the VLAN and enable it again (PD2-251147301).
The disable slot all Command Generates EDP Errors
If you have ESRP enabled, the disable slot all command generates EDP errors. You can safely
ignore the error messages (PD2-166105101).
Large Configurations Might Lock Console when Enabling and Disabling s0
If you have more than 60 STP domains with more than 200 tagged VLANs between them and more
than 6 ports in each, and you enable then immediately disable s0, the console might freeze for up to a
minute. Larger networks cause the console to remain locked for longer periods. The switch is still
operating, and the console unlocks after the processing finishes. To work around this, either wait before
disabling s0, or wait until the console unlocks (PD2-159834277, PD2-151426418).
ESRP and Protocol-Based VLANs
ESRP-aware switches cannot connect to an ESRP switch through a port configured for a
protocol-sensitive VLAN using untagged traffic (PD2-99007701).
ESRP and Load Sharing
If you enable load sharing on ports that belong to more than 200 VLANs, the switch reboots. To avoid
this, first enable load sharing, then add the ports to the VLANs (PD2-99259801).
Hot-Swapping a Module with 5,000 ACLs
Hot-swapping a module on a switch that has 5,000 or more ACLs configured can cause an ESRP state
change (PD2-107800998, PD2-103938301). To avoid the state change, configure the neighbor timeout
value to 12 seconds.
Traffic Convergence Time
Traffic convergence after a link failure can take as long as 5 seconds with 2,000 VLANs and 256,000 FDB
entries. This delay can cause ESRP state changes as traffic converges (PD2-89915300).
ESRP PDUs on Ports
ESRP PDUs received on ports that do not belong to any VLAN are processed as valid ESRP PDUs and
can trigger state changes (PD2-89481346). To avoid this, assign all ports to valid VLANs with matching
tags.
