Channelized Port Output Fields
Channelized Port Output —
The following table describes channelized port output fields.
Label
Description
Description
A text description of the port.
Interface
The port ID displayed in the
slot/mda/port
format.
TimeSlots
Specifies the DS0 timeslot used in the T1/E1 channel-group.
Speed
Indicates the speed of the DS0 channels used in the associated channel-
group.
CRC
Indicates the precision of the cyclic redundancy check.
16 —
A16-bit CRC calculation.
32 —
A 32-bit CRC calculation. 32-bit CRC increases the error
detection ability, but it also adds some performance overhead.
Admin Status
Up —
The port is administratively up.
Down —
The administratively down.
Oper Status
Up —
The port is operationally up.
Down —
The port is operationally down.
Last State Change
Displays the last time the operational status of the port changed state.
Chan-Grp IfIndex
Displays the channel group’s interface index number which reflects its
initialization sequence.
Configured Mode
network —
The port is configured for transport network use.
access —
The port is configured for service access. Channelized
ports are always access ports.
Encap Type
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.
Oper MTU
The negotiated size of the largest packet which can be sent on the chan-
nel, 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.
Physical Link
Indicates whether or not the port has a physical link.
U
nicast Packets
Input/Output
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.
