Chapter 2: Bridging Configuration Guide
Configuring VLAN Trunk Ports
The IA supports standards-based VLAN trunking between multiple IAs as defined by
IEEE 802.1Q. 802.1Q adds a header to a standard Ethernet frame that includes a unique
VLAN ID per trunk between two IAs. These VLAN IDs extend the VLAN broadcast
domain to more than one IA.
To configure a VLAN trunk, enter the following command in the Configure mode.:
Configure 802.1Q VLAN trunks.
Configuring VLANs for Bridging
The IA allows you to create VLANs for AppleTalk, DECnet
well as for IP traffic. You can create a VLAN for handling traffic for a single protocol, such
as a DECnet VLAN, or you can create a VLAN that supports several specific protocols,
such as SNA and IP traffic.
Monitoring Bridging
The IA provides a display of bridging statistics and configurations contained in the IA.
To display bridging information, enter the following commands in Enable mode:
Show IP routing table.
Show all MAC addresses currently
in the l2 tables.
Show l2 table information on a
specific port.
Show information the master MAC
table.
Show information on a specific
MAC address.
Show information on MACs
registered.
Show all VLANs.
