Operation Manual – Link AggregationH3C S3100-52P Ethernet Switch Chapter 1 Link Aggregation Configuration1-81.2 Link Aggregation ConfigurationCaution:z The commands of link aggregation cannot be configured with the commands of portloopback detection feature at the same time.z The ports where the mac-address max-mac-count command is configured cannotbe added to an aggregation group. Contrarily, the mac-address max-mac-countcommand cannot be configured on a port that has already been added to anaggregation group.z MAC-authentication-enabled ports and 802.1x-enabled ports cannot be added to anaggregation group.z Mirroring destination ports and mirroring reflector ports cannot be added to anaggregation group.z Ports configured with blackhole MAC addresses, static MAC addresses or the staticARP protocol cannot be added to the aggregation group.z Ports where the IP-MAC address binding is configured cannot be added to anaggregation group.z Port-security-enabled ports cannot be added to an aggregation group.1.2.1 Configuring a Manual Aggregation GroupYou can create a manual aggregation group, or remove an existing manual aggregationgroup (after that, all the member ports in the group are removed from the ports).For a manual aggregation group, a port can only be manually added/removed to/fromthe manual aggregation group.Table 1-1 Configure a manual aggregation groupOperation Command DescriptionEnter system view system-view —Create a manualaggregation grouplink-aggregation groupagg-id mode manual RequiredConfigure a descriptionfor the aggregationgrouplink-aggregation groupagg-id descriptionagg-nameOptionalBy default, an aggregationgroup has no description.Enter Ethernet port view interface interface-typeinterface-number —
