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.
loopguard policy
fix|dynamic
Sets which action to take when a loop condition is detected on one of
the specified DSL ports.
fix
: shut down the port, you need to enable the port by command
dynamic
: shutdown the port, and recover it after the recover time
C 13
loopguard recover-time
< time >
Configures the recover time for the dynamic loop guard policy.
time
: 60-600 in seconds
C 13
loopguard uni-vlan < vid >
[pbit < pbit >]
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
C 13
no loopguard uni-vlan
Removes the VID and IEEE 802.1p priority bit settings that the IES
uses to detect loopguard packets. C 13
no loopguard
Disables loop guard. C 13
