Operation Manual – Link AggregationH3C S5600 Series Ethernet Switches Chapter 1 Link Aggregation Configuration1-71.4 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, multicastMAC addresses, or the static ARP protocol cannot be added to an aggregationgroup.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.z The port with Voice VLAN enabled cannot be added to an aggregation group.z Do not add ports with the inter-VLAN MAC address replicating function of theselective QinQ feature enabled to an aggregation group.z Do not add ports with IP filtering enabled to an aggregation group.z Do not add ports with ARP intrusion detection enabled to an aggregation group.z Do not add ports with source IP addresses/source MAC addresses statically boundto them to an aggregation group.z Web-authentication-enabled ports cannot be added to an aggregation group.1.4.1 Configuring a Manual Aggregation GroupYou can create a manual aggregation group, or remove an existing manual aggregationgroup (after that, all the member ports will be removed from the group).For a manual aggregation group, a port can only be manually added/removed to/fromthe manual aggregation group.
