set port discard
Enterasys G-Series CLI Reference 7-11
set port discard
Use this command to set the frame discard mode on one or more ports.
Syntax
set port discard port-string { tagged | untagged | both | none }
Parameters
Defaults
None.
Mode
Switch command, read ‐ write.
Usage
The options are to discard all incoming tagged frames, all incoming untagged frames, neither
(essentially allow all traffic), or both (essentially discarding all traffic).
A common practice is to discard all tagged packet on user ports. Typically an Administrator does
not want the end users defining what VLAN they use for communication.
Example
This example shows how to discard all tagged frames received on port ge .3.3:
G3(su)->set port discard ge.3.3 tagged
Configuring the VLAN Egress List
Purpose
To assign or remove ports on the egress list of a particular VLAN. This determines which ports on
the switch will be eligible to transmit frames for a particular VLAN. For example, ports 1, 5, 7, 8
could be allowed to transmit frames belonging to VLAN 20 and ports 7,8, 9, 10 could be allowed to
transmit frames tagged with VLAN 30 (a port can belong to multiple VLAN Egress lists). Note
that the Port Egress list for ports 7 and 8 would contain both VLAN 20 and 30.
The port egress type for all ports can be set to tagged, forbidden, or untagged. In general, VLANs
have no egress (except for VLAN 1) until they are configured by static administration, or through
dynamic mechanisms such as GVRP.
port ‐ string Specifies the port(s) for which to set frame discard mode. For a detailed
description of possible port ‐ string values, refer to “ Port String Syntax Used
in the CLI ” on page 4 ‐ 1.
