13.7.1 Command Examples

This example shows port 1 on slot 2 is disabled, then enables the port and loop guard on it as well.
It also sets the IES to shut down port 1 if it detects a loop on it on VLAN 100 and wait 300 seconds
before reactivating it. This example also shows whether the port has linked up with the connected
CPE port, loop guard status, sending and receiving packet statistics, and the date and time this port
was last shut down.

DESCRIPTION
Sets which action to take when a loop condition is detected on one of
the specified DSL ports.
: shut down the port, you need to enable the port by command
fix
: shutdown the port, and recover it after the recover time
dynamic
Configures the recover time for the dynamic loop guard policy.
: 60-600 in seconds
time
Tells the IES what VID (and optionally IEEE 802.1p priority bit) to look
for to detect loopguard packets. Detecting the loopguard packets fails if
the VLAN mode you configured (through vlan trunk for example) does
not match the loopguard VID.
vid: 1 ~ 4093
pbit: 0~7, default 6
Removes the VID and IEEE 802.1p priority bit settings that the IES
uses to detect loopguard packets.
Disables loop guard.
