13.4.2 Port Channel Troubleshooting Help
If problems occur when configuring port aggregation, please first check the following for causes.
&
Ensure all ports in a port group have the same properties, i.e., whether they are in full-duplex
mode, forced to the same speed, and have the same VLAN properties, etc. If inconsistency
occurs, make corrections.
&
Some commands cannot be used on a port in port-channel, such as arp, bandwidth, ip,
ip-forward, etc.
&
When port-channel is forced, as the aggregation is triggered manually, the port group will stay
unaggregated if aggregation fails due to inconsistent VLAN information. Ports must be added
to or removed from the group to trigger another aggregation, if VLAN information
inconsistency persists, the aggregation will fail again. The aggregation will only succeed when
VLAN information is consistent and aggregation is triggered due to port addition or removal.
&
Verify that port group is configured in the partner end, and in the same configuration. If the
local end is set in manual aggregation or LACP, the same should be done in the partner end;
otherwise part aggregation will not work properly. Another thing to note is that if both ends are
configured with LACP, then at least one of them should be in ACTIVE mode, otherwise LACP
packet won’t be initialed.
&
LACP cannot be used on ports with Security and IEEE 802.1x enabled.
13.5 WEB MANAGEMENT
Click “Port channel configuration” to open LACP port group configuration and LACP port
configuration. LACP port group page will be used to configure and display group while LACP port
configuration page will be used to configure and display port group members.
13.5.1 LACP port group configuration
Click “LACP port group configuration” to enter configuration page. Equivalent to CLI command
13.2.2.1.
