set port ingress-filter
Enterasys C3 Configuration Guide 14-11
set port ingress-filter
Use this command to discard all frames received with a VLAN ID that don’t match the port’s
VLAN egress list.
Syntax
set port ingress-filter port-string {disable | enable}
Parameters
Defaults
None.
Mode
Switch command, read-write.
Usage
When ingress filtering is enabled on a port, the VLAN IDs of incoming frames are compared to the
port’s egress list. If the received VLAN ID does not match a VLAN ID on the port’s egress list, then
the frame is dropped.
Ingress filtering is implemented according to the IEEE 802.1Q standard.
Example
This example shows how to enable port ingress filtering on ge.1.3:
C3(su)->set port ingress-filter ge.1.3 enable
show port discard
Use this command to display the frame discard mode for one or more ports. Ports can be set to
discard frames based on whether or not the frame contains a VLAN tag. They can also be set to
discard both tagged and untagged frames, or neither.
Syntax
show port discard [port-string]
Parameters
Defaults
If port-string is not specified, frame discard mode will be displayed for all
ports.
port-string Specifies the port(s) on which to enable of disable ingress filtering. For a
