Chapter 6
* Note: When VTP Snooping creates VLANs on the Avaya
Multiservice switches, the hash table size for the VLANs is
automatically set to 64. Depending on the number of VLANs
that are created, you may need to manually change this hash
table setting. For information on the relationship between hash
table sizes and the number of VLANs that are configured on
the switch, see “
Relationship between VLANs, AFT and Hash
Table Sizes ,” in Chapter 9 , “ Managing the Address Forwarding
Table .”
VTP Snooping is Disabled by default. You only need to change VTP
Snooping port settings if you want to Enable its ability to learn VLAN
changes from a Cisco VTP server.
You can configure VTP snooping from either the Web Agent or the CLI.
Web Agent
Procedure
To configure VTP snooping using the Web Agent:
1. Select Configuration from the Modules & Ports folder on the Web
Agent window. The Module Information window opens (see Figure 6-
11 ).
2. Select the number in the Switch Ports column for the module you want
to configure VTP. The Switch Ports window for that module opens
(see
Figure 6-13 ).
3. Select the port in the Name column on which you want to enable VTP
Snooping throughout the switch. The Switch Port Configuration
window opens for that port (see
Figure 6-14 ).
4. Select either IEEE 802.1Q or Multi-layer from the Trunk Mode pull-
down menu to match the setting of the trunk mode for the switch port at
the other end of the link.
5. Select Enable from the VTP Snooping pull-down menu. This enables
VTP snooping on the switch port.
6. Click APPLY to save your changes, or CANCEL to restore previous
settings.
7. Select VTP Snooping from the L2 Switching > VLANs folder on the
Web Agent window. The VTP Snooping Configuration window opens
(see
Figure 6-16 ).
