Configuring VLAN Trunk Ports
The GSR supports standards-based VLAN trunking between multiple GSRs as defined by
IEEE 802.1Q. 802.1Q adds a header to a standard Ethernet frame which includes a unique
VLAN id per trunk between two GSRs. These VLAN IDs extend the VLAN broadcast
domain to more than one GSR.
To configure a VLAN trunk, enter the following command in the Configure mode.
Configuring VLANs for Bridging
The GSR allows you to create VLANs for AppleTalk, DECnet
®
, SNA, and IPv6 traffic as
well as for IP and IPX 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.
Note:
Some commands in this facility require updated GSR hardware. Please refer to the
Release Notes for details.
Configuring Layer-2 Filters
Layer-2 security filters on the GSR allow you to configure ports to filter specific MAC
addresses. When defining a Layer-2 security filter, you specify to which ports you want
the filter to apply. Refer to the
“Security Configuration Chapter” for details on configuring
Layer-2 filters. You can specify the following security filters:
• Address filters
These filters block traffic based on the frame's source MAC address, destination MAC
address, or both source and destination MAC addresses in flow bridging mode.
Address filters are always configured and applied to the input port.
• Port-to-address lock filters
These filters prohibit a user connected to a locked port or set of ports from using
another port.
• Static entry filters
These filters allow or force traffic to go to a set of destination ports based on a frame's
source MAC address, destination MAC address, or both source and destination MAC
addresses in flow bridging mode. Static entries are always configured and applied at
the input port.
