Example #4: Enable IGMP Snooping Querier on a VLAN To configure IGMP Snooping Querier on a VLAN, enter VLAN Database mode. The first ip igmp snooping command in this example enables the IGMP snooping querier on VLAN 10. The second ip igmp snooping command specifies the IP address that the snooping querier switch should use as source address when generating periodic queries. The final command enables the Snooping Querier to participate in the Querier Election process when it discovers the presence of another Querier in the VLAN. NOTE: For IGMP Snooping Querier functionality to be operationally enabled on the VLAN, IGMP Snooping and IGMP Snooping Querier must both be enabled globally on the switch. console(config)#vlan database console(config-vlan)#ip igmp snooping querier 10 console(config-vlan)#ip igmp snooping querier 10 address 10.10.11.40 console(config-vlan)#ip igmp snooping querier election participate 10 Example #5: Show IGMP Snooping Querier Information for VLAN 10 console#show ip igmp snooping querier vlan 10 Vlan 10 : IGMP Snooping querier status IGMP Snooping Querier Vlan Mode Enable Querier Election Participate Mode Enable Querier Vlan Address 10.10.11.40 Operational State Querier Operational version 2 Operational Max Resp Time 10 Link Aggregation/Port Channels This section shows how to use the Link Aggregation feature to configure port-channels via the Command Line Interface and the Graphical User Interface. The Link Aggregation (LAG) feature allows the switch to treat multiple physical links between two endpoints as a single logical link called a port-channel. All of the physical links in a given port-channel must operate in full-duplex mode at the same speed. You can use the feature to directly connect two switches when the traffic between them requires high bandwidth and reliability, or to provide a higher bandwidth connection to a public network. You can configure the port-channels as either dynamic or static. Dynamic configuration uses the IEEE 802.3ad standard, which provides for the periodic exchanges of LACPDUs. Static configuration is used when connecting the switch to an external switch that does not support the exchange of LACPDUs. The feature offers the following benefits: • Increased reliability and availability: If one of the physical links in the port-channel goes down, traffic is dynamically and transparently reassigned to one of the other physical links.

To configure IGMP Snooping Querier on a VLAN, enter VLAN Database mode. The first

command in this example enables the IGMP snooping querier on VLAN 10. The second
ip
igmp snooping

participate in the Querier Election process when it discovers the presence of another Querier in the

NOTE:
For IGMP Snooping Querier functionality to be operationally enabled on the VLAN, IGMP Snooping and
IGMP Snooping Querier must both be enabled globally on the switch.

Link Aggregation/Port Channels
This section shows how to use the Link Aggregation feature to configure port-channels via the
Command Line Interface and the Graphical User Interface.
The Link Aggregation (LAG) feature allows the switch to treat multiple physical links between two end-
points as a single logical link called a port-channel. All of the physical links in a given port-channel must
operate in full-duplex mode at the same speed.
You can use the feature to directly connect two switches when the traffic between them requires high
bandwidth and reliability, or to provide a higher bandwidth connection to a public network.
You can configure the port-channels as either dynamic or static. Dynamic configuration uses the IEEE
802.3ad standard, which provides for the periodic exchanges of LACPDUs. Static configuration is used
when connecting the switch to an external switch that does not support the exchange of LACPDUs.
The feature offers the following benefits:
•
Increased reliability and availability: If one of the physical links in the port-channel goes down, traffic is
dynamically and transparently reassigned to one of the other physical links.
