Caution Note Troubleshooting Unusual Network Activity IP Multicast Traffic Floods Out All Ports; IGMP Does Not Appear To Filter Traffic. The IGMP feature does not operate if the switch or VLAN does not have an IP address configured manually or obtained through DHCP/Bootp. To verify whether an IP address is configured for the switch or VLAN, do either of the following: ■ Try Using the Web Browser Interface: If you can access the web browser interface, then an IP address is configured. ■ Try To Telnet to the Switch Console: If you can Telnet to the switch, then an IP address is configured. ■ Using the Switch Console Interface: From the Main Menu, check the Management Address Information screen by clicking on 1. Status and Counters 2. Switch Management Address Information LACP-Related Problems Unable to enable LACP on a port with the interface < port-number > lacp command. In this case, the switch displays the following message: Operation is not allowed for a trunked port. You cannot enable LACP on a port while it is configured as static Trunk port. To enable LACP on static-trunked port, first use the no trunk < port-number > command to disable the static trunk assignment, then execute interface < port-number > lacp. Removing a port from a trunk without first disabling the port can create a traffic loop that can slow down or halt your network. Before removing a port from a trunk, ProCurve recommends that you either disable the port or disconnect it from the LAN.
