set vlan dynamicegress
7-16 802.1Q VLAN Configuration
set vlan dynamicegress
Use this command to administratively set the dynamic egress status for one or more VLANs.
Syntax
set vlan dynamicegress vlan-list {enable | disable}
Parameters
Defaults
None.
Mode
Switch command, read ‐ write.
Usage
If dynamic egress is enabled for a particular VLAN, when a port receives a frame tagged with that
VLAN’s ID, the switch will add the receiving port to that VLAN’s egress list. Dynamic egress is
disabled on the G ‐ Series by default.
For example, assume you have 20 AppleTalk users on your network who are mobile users (that is,
use different ports every day), but you want to keep the AppleTalk traffic isolated in its own
VLAN. You can create an AppleTalk VLAN with a VLAN ID of 55 with a classification rule that all
AppleTalk traffic gets tagged with VLAN ID 55. Then, you enable dynamic egress for VLAN 55.
Now, when an AppleTalk user plugs into port ge .3.5 and sends an AppleTalk packet, the switch
will tag the packet to VLAN 55 and also add port ge .3.5 to VLAN 55’s egress list, which allows the
AppleTalk user to receive AppleTalk traffic.
Example
This example shows how to enable dynamic egress on VLAN 55:
G3(rw)->set vlan dynamicegress 55 enable
Setting the Host VLAN
Purpose
To configure a host VLAN that only select devices are allowed to access. This secures the host port
for management ‐ only tasks.
vlan ‐ list Specifies the VLANs by ID to enable or disable dynamic egress.
enable | disable Enables or disables dynamic egress.
Note: The host port is the management entity of the device. Refer to “ Creating a Secure
Management VLAN ” on page 7-1 for more information.
