• Use the ifconfig -a command to display the interface configuration. The Linux kernel port numbers that correspond to front-panel port, port-channel, and VLAN interfaces are displayed. Port-channel interfaces are in boportchannel-number format. VLAN interfaces are in brvlan-id format. In this example, e101-001-0 identifies port 1/1/1.

  admin@OS10:~# ifconfig -a

• Use the tcpdump -i kernel-port-number command to capture all packets received on a specified port interface. Press Ctrl+C to stop the packet output display. For example, to capture the packets received on the Ethernet 1/1/1 interface, enter:

  admin@OS10:~# tcpdump -i e101-001-0 
  tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
  listening on e101-001-0, link-type EN10MB (Ethernet), capture size 262144 bytes

• Run show commands remotely using an SSH session. Only show commands are supported.
  Enter the $ ssh admin@ip-address "show-command" command, where ip-address is the IP address of the switch.

  $ ssh admin@10.11.98.39 "show version"
