Hello, I'm not surre how it works on UC520, but with 3750 (for example) when you don't have a spanning tree instance for that vlan then the interface state is up/down.
3750-1#sh spanning-tree vlan 24 Spanning tree instance(s) for vlan 24 does not exist. 3750-1#sh int vlan 24 | i Vlan Vlan24 is up, line protocol is down When enabling spanning tree 3750-1#sh spanning-tree vlan 24 VLAN0024 Spanning tree enabled protocol ieee 3750-1#sh int vlan 24 | i Vlan|Internet address Vlan24 is up, line protocol is up Internet address is 1.2.3.4/24 3750-1#ping 1.2.3.4 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 1.2.3.4, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5) Regards, David On 10/1/08, Bagosi Rómeó <[EMAIL PROTECTED]> wrote: > Hi, > > Is there a way to force a VLAN interface (ex.: interface vlan 400) to UP/UP > state on a Cisco UC520 (router, switch...), WITHOUT connecting a device to a > port which is in the mentioned VLAN? > > The current configuration is: > int vlan 400 > ip address 10.1.1.1 255.255.255.0 > > show int vlan 400 > Vlan300 is up, line protocol is down > ... > > Thanks, > Romeo Bagosi > > _______________________________________________ > cisco-nsp mailing list [email protected] > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
