Error Message
STP-2-VLAN_PORT_LIMIT_EXCEEDED: The number of vlan-port instances
exceeded [[chars] mode] recommended limit of [dec]
Explanation
The total number of individual VLAN ports, in the spanning tree mode specified in the
error message, has exceeded the limit specified in the error message. VLANs can be counted more
than once; if VLAN 1 is carried on 10 interfaces, it will count as 10 VLAN ports. Note that bundling
is igored for purposes of this count; if 8 interfaces on the same module are in one bundle, and the
port channel is carrying VLAN 1, it will count as 1 VLAN ports.
Recommended Action
Reduce the number of trunks and VLANs configured in the switch. Keep the
VLAN port count below the recommended limit specified in the configuration documentation. Enter
the <CmdBold>show interface trunk<NoCmdBold> command to see the total number of trunks and
VLANs.
