Detailed Port Output Fields Detailed Port Output — The following table describes detailed port output fields.
Label Description
Description
A text description of the port.
Interface
The port ID displayed in the slot/mda/port format.
Speed
The speed of the interface.
Link-level
Ethernet — The port is configured as Ethernet.
SONET — The port is configured as SONET/SDH.
MTU
The size of the largest packet which can be sent/received on the
Ethernet physical interface, specified in octets.
Admin State
Up — The port is administratively up.
Down — The port is administratively down.
Oper State
Up — The port is operationally up.
Down — The port is operationally down.
Duplex
Full — The link is set to full duplex mode.
Half — The link is set to half duplex mode.
Hold time up
The link up dampening time in seconds. The port link dampening
timer value which reduces the number of link transitions reported to
upper layer protocols.
Hold time down
The link down dampening time in seconds. The down timer controls
the dampening timer for link down transitions.
IfIndex
Displays the interface's index number which reflects its initialization
sequence.
Phy Link
Yes — A physical link is present.
No — A physical link is not present.
Phys State Chng
Cnt
Increments when a fully qualified (de-bounced) transition occurs at
the physical layer of an ethernet port which includes the following
transitions of the Port State as shown in the “show port” summary:
- from “Down” to either “Link Up” or “Up”
- from either “Link Up” or “Up” to “Down”
This counter does not increment for changes purely in the link
protocol states (e.g. "Link Up" to "Up"). The counter is reset if the
container objects for the port are deleted (e.g. MDA deconfigured, or
IOM type changes).
Last Cleared
Time
Displays the system time moment that the peer is up.
