Hello,
I have got a problem getting a multi vlan port to work properly on a C2924XL (IOS 12.0(5)XU). I often experience loss of connectivity between the server ONE plugged into that multi vlan port (#1) and other servers plugged into the single vlan ports (so far all on vlan 1, nothing is plugged into the vlan 2 ports yet). The switch is not connected to other switches, no trunking is enabled.
Perhaps someone is able to help.
The layout is such:
Port#1 is set up for vlan 1 and 2, all other ports are set up for vlan 1 or 2 only.
interface FastEthernet0/1
description ONE
switchport multi vlan 1,2
switchport mode multi
spanning-tree portfast
vlan 1 and 2 are setup:
VLAN ISL Id: 1
Name: default
Media Type: Ethernet
VLAN 802.10 Id: 100001
State: Operational
MTU: 1500
Translational Bridged VLAN: 1002
Translational Bridged VLAN: 1003
VLAN ISL Id: 2
Name: PLC-LAN
Media Type: Ethernet
VLAN 802.10 Id: 100002
State: Operational
MTU: 1500
When I boot the servers more often than not the server ONE is only able to connect(ping/telnet) to the switch, not to the other servers. At the same time the switch is able to ping all servers, including ONE. When I plug the server ONE into any
other port I have instant connectivity to the other servers.
Has anyone an idea what is going wrong?
Thanks a lot
Dorothea
