Label
A text description of the port.
The port ID displayed in the slot/mda/port format.
Specifies the DS0 timeslot used in the T1/E1 channel-group.
Indicates the speed of the DS0 channels used in the associated channel-
group.
Indicates the precision of the cyclic redundancy check.
— A16-bit CRC calculation.
16
— A 32-bit CRC calculation. 32-bit CRC increases the error detection

ability, but it also adds some performance overhead.
Up — The port is administratively up.
Down — The administratively down.
Up — The port is operationally up.
Down — The port is operationally down.
Displays the last time the operational status of the port changed state.
Displays the channel group's interface index number which reflects its
initialization sequence.
network — The port is configured for transport network use.
access — The port is configured for service access. Channelized ports
are always access ports.
The type of encapsulation protocol configured on this port's network
interface.
bcp-null — Indicates that BCP is used as the NCP control protocol.
dot1q — Indicates that ingress frames carry 802.1Q tags where each tag
signifies a different service.
The negotiated size of the largest packet which can be sent on the channel,
specified in octets. For channels that are used to transmit network
datagrams, this is the size of the largest network datagram that can be sent.
Indicates whether or not the port has a physical link.
The number of packets, delivered by this sub-layer to a higher (sub-) layer,
which were not addressed to a multicast or broadcast address at this sub-
layer.
