This Trunk Link has ports with mismatching active VLAN sets.

Tivella present in VTP domain ABC and having index 202
7A1 present in VTP domain ABC and having index 101
7A9 present in VTP domain ABC and having index 33
4A present in VTP domain ABC and having index 106
3A1 present in VTP domain ABC and having index 108
trnet-default present in VTP domain ABC and having index 1005
default present in VTP domain ABC and having index 1
2M present in VTP domain ABC and having index 152
6A present in VTP domain ABC and having index 104
BA present in VTP domain ABC and having index 111
1M present in VTP domain ABC and having index 151
1A present in VTP domain ABC and having index 110
7A8 present in VTP domain ABC and having index 90


Port 5/2 on device 7A6509-1 trunks following VLANs:
7A5 present in VTP domain ABC and having index 32
default present in VTP domain ABC and having index 1
Tivella present in VTP domain ABC and having index 202
Mainframe2 present in VTP domain ABC and having index 61
Mainframe1 present in VTP domain ABC and having index 60

Port 5/2 on device 7A6509-1 does not trunk the following VLAN indices:
Index:108
Index:109
Index:110
Index:111
Index:112
Index:150
Index:151
Index:152
Index:153
Index:154
Index:514
Index:155
Index:90
Index:200
Index:201
Index:203
Index:100
Index:101
Index:102
Index:103
Index:104
Index:1005
Index:105
Index:33
Index:106
Index:107

Note: This discrepancy does not hold good if devices on either end of the trunk support different number of vlans.

For trunk links to form properly, both sides should have the same VLANs configured across the trunk. If not, you'll see connectivity problems and the trunk may not even form. By default a trunk will carry all VLANs unless there is pruning or the administrator manually configures allowed VLANs. CiscoWorks is telling you do fix the trunks to carry the same VLANs on each side.

Hi, Cluebird
thanks, but how can I fix it?

 

[Cluebird]

Configure both sides of the trunk link to carry the same VLANs.

If your 6509 is a CATOS device, you add and delete VLANS from the trunks as follows:

set trunk 1/1 250
(this adds vlan 250 to trunk 1/1)

clear trunk 1/1 100
(this deletes vlan 100 from trunk 1/1)

Verify changes with 'show trunk 1/1'

If your 6509 is an IOS device:

int fa1/1
switchport trunk allowed vlan add 250
(this adds vlan 250 to trunk 1/1)

int fa1/1
switchport trunk allowed vlan remove 100
(this deletes vlan 100 from trunk 1/1)

Verify changes with 'show int fa1/1 trunk'
