Description Use this command to display network interface status. If the operand
ifName
is provided, only that interface is displayed. If
ifName
is omitted,
all interfaces are displayed.
Each switch has three interfaces:
“ei” or “fei” is the 10BaseT or 100BaseT Ethernet interface.
“lo” is the loopback interface.
“fc” is the fibre channel interface.
The “fc” interface is displayed for switches running IP over fibre channel
that have been assigned an FC-IP address.
For each interface selected, the following information is displayed:
• flags (for example, loopback, broadcast, arp, running, debug)
• internet address
• broadcast address
• netmask and subnetmask
• Ethernet address
• route metric
• maximum transfer unit
• number of packets received and sent
• number of input errors, output errors, and collisions
