VLAN interface limit

Hello,

I have Cisco WS-C6509 with IOS version 12.2(18)

I have several vlan interface on this device.

Today I create new vlan intervace

interface Vlan165

description test5

ip address 10.10.10.1 255.255.255.252

end

and vlan:

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

165  test5                                 active    Gi7/14

But I can't ping this IP address and show ip route shows:

sh ip route 10.10.10.1

Routing entry for 10.10.10.0/24

  Known via "static", distance 254, metric 0 (connected)

I have static route for this subnet /24

I can not see any error in logs, but looks like I reached vlan interface limit on this device or something like this.

How can I check it?

Thanks.

VLAN interface limit

Hi,

You should refer to the datasheet of the Supervisor Engine being used in this chassis. That should clearly declare the max limit of VLANs on the switch, but if you are able to create the new VLAN then issue is not related to number of VLANs. please cross check your config once again bcoz IP on interface is /30 subnet whereas in routing table its /24.

Hi,

I made one more test with new vlan and new network:

cisco#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

cisco(config)#vlan 201

cisco(config-vlan)#name test6

cisco(config-vlan)#int vl 201

cisco(config-if)#ip address 12.12.12.1 255.255.255.252

cisco(config-if)#no shutdown

cisco(config-if)#^Z

cisco#sh run int vl 201

Building configuration...

Current configuration : 64 bytes

!

interface Vlan201

ip address 12.12.12.1 255.255.255.252

end

cisco#sh vl id 201

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

201  test6                            active   

cisco#sh ip route 12.12.12.1

% Network not in table

Thanks

Please map at least one switch port to Vlan201 and check.

Hi,

Any port into this VLAN has also be into UP state, Means you need to have some active device connected to it.

VLAN interface limit

Hi Vijay,

output was:

Vlan201 is down, line protocol is down

  Hardware is EtherSVI, address is 00d0.032a.740a (bia 00d0.032a.740a)

  Internet address is 12.12.12.1/30

after that I executed - "shutdown" and "no shutdown" on vlan interface 201 and all is fine.

Vlan interface is up and network are in table.

Thanks all.
