However, all traffic from the same source MAC address will use the same port in the channel. Therefore, if a device generates a large amount of traffic, the corresponding link will be utilized more than the rest of the links in the channel. In this case, the load should probably be balanced based on the destination address or source and destination addresses.Practical experience To properly configure load balancing for a channel, you must be familiar with the traffic patterns in the network. Once you are familiar with the traffic patterns, you can select the correct type of load balancing to make the best use of the channel.13,4.2 Configuring EtherChannelAs mentioned earlier, you must ensure that all interfaces in the channel are configured identically (the configuration of interface attributes is discussed in Chapter 10), otherwise the channel may not be established. The following is the configuration for establishing an EtherChannel.Switch(config)# interface type [slot_#/]port_# Switch(config-if)#channel-group group_# mode mode Switch(config-if)#port-channelload- balance (dst-ip | dst-mac |src-dst-ip I src-dst-mac |src-ip |src-mac}group_# specifies the channel group to which the interface belongs and takes a value in the range of 1.6 (as mentioned earlier, the switch can contain up to 6 EtherChannels ) o The mode can be one of the values listed in Table 13.4. When using PAgP, you must either configure the mode on one end as desirable and the mode on the other end as desirable or auto, or you must configure the mode on both ends as on; when using LACP, you must set the mode on one end as active and the mode on the other end as active or passiveoExam Essentials To assign an IP address to a channel port as you would for a router's Layer 3 interface, you must use the command interfaceport-channel group_# to switch to the configuration mode for that interface.Table 13.4 EtherChannel Mode Mode Protocol Descriptionauto PAgP passively listens for PAgP queries from Cisco devices with mode desirable or on. By default, the interface is not part of the channeldesirable PAgP Generates PAgP queries to establish the channel, but by default the interface is not part of the channel
