Line Description
• Vlans = number of VLAN tagged packets
• throttles = packets containing PAUSE frames
• discarded = number of packets discarded without any processing
• collisions = number of packet collisions
• wred=count both packets discarded in the MAC and in the hardware-based
queues
Rate
information...
Estimate of the input and output traffic rate over a designated interval (30 to 299
seconds). Traffic rate is displayed in bits, packets per second, and percent of line rate.
Time since... Elapsed time since the last interface status change (hh:mm:ss format).

Usage Information
The Management port is enabled by default (no shutdown). If necessary, use the ip address command to
assign an IP address to the Management port. If two RPMs are installed in your system, use the show
redundancy command to display which RPM is the Primary RPM.
You can configure two global IPv6 addresses. To view the addresses, use the show interface
managementethernet command. If you try to configure a third IPv6 address, a message displays. If auto-
configuration is enabled, all IPv6 addresses on that management interface are auto-configured. The first IPv6
address that is configured on the management interface is the primary address. If deleted, it must be re-added;
the secondary address is not promoted.
To view information on a specific PE stack-unit, use the show interface pe pe-id stack unit unit-
number command. You can use the show interfaces peGigE command to view the information on all the
components of the PE Gigabit Ethernet interface. You can use the show interfaces peTenGigE command
to view the information on all the components of the PE 10–Gigabit Ethernet interface.
To view the show output for multiple ports of a specified slot at a time, you can specify any random port number
or a range of ports, or a combination of both.
To specify a port range, you can enter a hyphenated range of one or more port range values separated with
commas; for example, show interfaces FortyGigE 1/0-4,7,9-11. To enter any random number of
