3Com 3226, 3250 manual SFP Modules, IP Configuration and Routing

8SUPERSTACK® 3 SWITCH 3226 AND SWITCH 3250 SOFTWARE VERSION

No more ports may be added to aggregated

link.

You should check the configuration of the following items on the physical port

■port security is disabled on the port.

■The VLAN membership of the port matches that of the aggregated link

■LACP is disabled.

■No ACL is bound to the port.

■If you attempt to enable LACP on a port which is currently a manual member of a link aggregation then the following error will be displayed:

Failed to set port 1:50 lacp status

If you wish the ports to automatically form a trunk using LACP then the ports must first be removed from the manual aggregation.

■If a trunk is disabled by using the bridge linkAggregation modify linkState CLI command then the physical trunk member ports for the aggregation will be disabled. A side effect of the ports being disabled is that they will no longer negotiate to become LACP-trunk members. If the trunk was formed by LACP then the trunk will disappear because it no longer has any member ports.

If the LACP trunk is disabled as above then attempting to enable the trunk with the linkState command will respond with an error that the trunk can not be configured. In order to form the LACP trunk you must manually re-enable the individual trunk member ports using the

SFP Modules

When adding or removing SFP modules the switch will reset a number of port parameters. 3Com recommends that you verify the following port parameters after adding or removing an SFP module:

■Media configuration (auto negotiation, speed and duplex)

■Link Aggregation membership.

■LACP state.

■Spanning tree port parameters.

■VLAN membership.

IP Configuration and Routing

■The Switch is optimized to operate as an edge router with a single default gateway acting as the next hop route to all other subnets.

■In larger networks it may take several minutes for the unit to learn the correct routing information. The unit may have to flush and relearn the routing information if there is a topology change in the network. During this time the network connectivity may be intermittent.

■In certain situations, the Switch will be unable to used hardware routing display the following error message in the system summary and route table:

Current network configuration requires use of

software routing, resulting in degraded

performance.
