Hi,

Got to Vlan database on your switch and use the command " no vlan 1003 tb-vlan1 tb-vlan2 ". This will work and take care of the problem.

HTH,

Hi Amit,

Thank for your replied.

vlan database

% Warning: It is recommended to configure VLAN from config mode,

as VLAN database mode is being deprecated. Please consult user

documentation for configuring VTP/VLAN in config mode.

29500(vlan)#no vlan 1003 tb-vlan1 tb-vlan2

Resetting translation bridge VLAN 1 to default

Resetting translation bridge VLAN 2 to default

2950(vlan)#exit

VLAN 1 TLB 2 VLAN 1003 has inconsistent TLB values (0 / 0)

APPLY failed.

Use 'abort' command to exit

2950(vlan)#

Too bad. I had tried this as well. Any clue?

amit-singh · ‎06-30-2005

Hi,

Please try the following steps and let me know. Please use the command " apply " to save the changes before using exit. Make sure that your switch is set a VTP server.

vlan database

(vlan)#no vlan 1 tb-vlan1 tb-vlan2

(vlan)#no vlan 1003 tb-vlan1 tb-vlan2

(vlan)#apply

(vlan)#exit

Let me know how it goes...

Hi Amit,

Couldn't remove. Any clue?

(vlan)#no vlan 1 tb-vlan1 tb-vlan2

Resetting translation bridge VLAN 1 to default

Resetting translation bridge VLAN 2 to default

(vlan)#no vlan 1003 tb-vlan1 tb-vlan2

Resetting translation bridge VLAN 1 to default

Resetting translation bridge VLAN 2 to default

(vlan)#apply

VLAN 1002 TLB 1 VLAN 1 has inconsistent TLB values (0 / 0)

APPLY failed.

(vlan)#

Please paste the output of "show curr " and show VTP status ".

the above message "VLAN 1002 TLB 1 VLAN 1 has inconsistent TLB values (0 / 0)" shows that there is a translation for vlan 1002 to vlan1. Try to use the same command to remove the translation to vlan 1002.

no vlan 1 tb-vlan1 tb-vlan2

no vlan 1002 tb-vlan1 tb-vlan2

These are default vlans , you cannot remove them.

1002-1005

Normal

Cisco defaults for FDDI and Token Ring. You cannot delete VLANs 1002-1005.
