• 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.

• 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

Using OS9 commands
To enter configuration commands using an OS9 command syntax, use the feature config-os9-style command in
CONFIGURATION mode and log out of the session. If you do not log out of the OS10 session, configuration changes made with OS9
command syntaxes do not take effect. After you log in again, you can enter OS9 commands, but only in the new session.
