DHCP_SNOOPING_CAT3550 Messages
This section contains the Catalyst 3550-specific DHCP snooping messages.
Error Message DHCP_SNOOPING_CAT3550-3-MVR_INSTALL: Cannot install [chars] ACLs for
DHCP Snooping, probably no TCAM space.
Note This message applies only to Catalyst 3550 switches.
Explanation When DHCP snooping is enabled, access control lists (ACLs) need to be installed in the
ternary content addressable memory (TCAM). DHCP snooping fails if there is insufficient space in
the TCAM.
Recommended Action Reduce the number of input or output port ACLs (PACLs) and VLAN maps to
make space in the
TCAM.
