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).
Failure of Direct Link Causes Flip
If you have a direct link between the master and slave switch, and that link fails, the master transitions
to slave and back to master. To avoid this, configure both load-sharing links to don’t count
(PD2-157406636, PD2-148539301).
ESRP and Ingress Rate Shaping
Do not use ingress rate shaping on an ESRP-enabled port (PD2-107800933).
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).
When using load sharing with the ESRP host attach or don't count features, configure all ports in the
same load-sharing group as host attach ports or don’t-count ports (PD2-97342427, PD2-106782876).
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.
Multiple ESRP VLANs
If multiple ESRP VLANs share a host port, each VLAN must be in a different ESRP group.
ELRP
ELRP and Ingress Rate Shaping
Do not use ingress rate shaping on an ELRP-enabled VLAN (PD2-133066184).
