ProSafe M4100 and M7100 Managed Switches When you specify a value for vlanid, the following information appears. Field Description VLAN Admin Mode Indicates whether MLD Snooping Querier is active on the VLAN. VLAN Operational State Indicates whether MLD Snooping Querier is in "Querier" or "Non-Querier" state. When the switch is in Querier state, it will send out periodic general queries. When in Non-Querier state, it will wait for moving to Querier state and does not send out any queries. Operational Max Response Time Indicates the time to wait before removing a Leave from a host upon receiving a Leave request. This value is calculated dynamically from the Queries received from the network. If the Snooping Switch is in Querier state, then it is equal to the configured value. Querier Election Indicates whether the MLD Snooping Querier participates in querier election if it Participate discovers the presence of a querier in the VLAN. Querier VLAN Address The IP address will be used in the IPv6 header while sending out MLD queries on this VLAN. It can be configured using the appropriate command. Operational Version This version of IPv6 will be used while sending out MLD queriers on this VLAN. Last Querier Address Indicates the IP address of the most recent Querier from which a Query was received. Last Querier Version Indicates the MLD version of the most recent Querier from which a Query was received on this VLAN. When the optional argument detail is used, the command shows the global information and the information for all Querier-enabled VLANs. Port Security Commands This section describes the commands you use to configure Port Security on the switch. Port security, which is also known as port MAC locking, allows you to secure the network by locking allowable MAC addresses on a port. Packets with a matching source MAC address are forwarded normally, and all other packets are discarded. Note: To enable the SNMP trap specific to port security, see snmp-server enable traps violation on page 673. Switching Commands 171
