* The command show interface is used to display information about the status, speed, duplex mode, and other parameters of the network interfaces on a device. It can also show the number of packets sent and received, the error rate, and the utilization rate of each interface.
* The command can help determine whether an LACP bundle is fully operational by showing the aggregated bandwidth, the load balancing method, the active and standby links, and the LACP protocol status of each interface in the bundle.
* LACP (Link Aggregation Control Protocol) is a protocol that allows multiple physical links to be combined into a logical link, or a bundle, to increase the bandwidth and provide redundancy. LACP is also known as IEEE 802.3ad or EtherChannel.
* The command show config is used to display the current configuration of the device, such as the hostname, the IP addresses, the routing protocols, the security settings, and the interface settings. It does not show the operational status of the interfaces or the LACP bundle.
* The command show route is used to display the routing table of the device, which contains the destination networks, the next-hop addresses, the interface names, and the metrics of the routes. It does not show the operational status of the interfaces or the LACP bundle.
* The command show arp is used to display the ARP (Address Resolution Protocol) cache of the device, which contains the mappings between the IP addresses and the MAC addresses of the devices on the local network. It does not show the operational status of the interfaces or the LACP bundle. References:
