set port discard
14-12 802.1Q VLAN Configuration
Mode
Switch command, read-only.
Example
This example shows how to display the frame discard mode for ge.2.7. In this case, the port has
been set to discard all tagged frames:
C3(su)->show port discard ge.2.7
Port Discard Mode
------------ -------------
ge.2.7 tagged
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:
C3(su)->set port discard ge.3.3 tagged
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 11-1.
