Last State Change

The last time that the operational status of the port changed state

Hold time down

The link-down dampening time in seconds. The down timer controls the dampening timer for link down transitions.

Last Cleared Time

The time since the last clear

Configured Mode

network — the port is configured for transport network use

access — the port is configured for service access

hybrid — the port is configured for hybrid use (transport network and service access per VLAN)

Encap Type

null — ingress frames will not use any tags or labels to delineate a service

dot1q — ingress frames carry 802.1Q tags, where each tag signifies a different service

qinq — ingress frames carry two 802.1Q tags, where the outer tag is the service provider tag and the inner tag is the customer service tag

Dot1Q Ethertype

The protocol carried in a dot1q Ethernet frame

QinQ Ethertype

The protocol carried in a QinQ Ethernet frame

Net.Egr. Queue Pol.

The number of the associated network egress queue QoS policy, or default if the default policy is used

Access Egr. QoS

Specifies the access egress policy or that the default policy 1 is in use.

Egr. Sched. Pol

Specifies the port scheduler policy or that the default policy default is in use.

Network Qos Pol

The QoS policy ID applied to the port.

Auto-negotiate

true — the link attempts to automatically negotiate the link speed and duplex parameters

false — the duplex and speed values are used for the link

MDI/MDX

Indicates the Ethernet interface type

Accounting Policy

The accounting policy applied to the port.

Collect-stats

Enabled — The collection of accounting and statistical data for the network Ethernet port is enabled. When applying accounting policies the data by default will be collected in the appropriate records and written to the designated billing file.

Disabled — Collection is disabled. Statistics are still accumulated by the IOM cards, however, the CPU will not obtain the results and write them to the billing file.

Egress Rate

The maximum amount of egress bandwidth (in kilobits per second) that this Ethernet interface can generate

Down-when-looped

Enabled — The down-when-looped feature is enabled on the port

Disabled — The down-when-looped feature is disabled on the port

Keep-alive

The time interval between keepalive PDUs transmitted toward the network during loop detection by the down-when-looped feature

Loop Detected

Indicates whether a loop is detected on the port

Retry

The minimum wait time before the port is re-enabled after it is brought down due to a loop detection

Configured Address

The base chassis Ethernet MAC address

Hardware Address

The interface hardware- or system-assigned MAC address at its protocol sublayer

The wavelength of the transmission laser

Diag Capable

Displays whether digital diagnostic monitoring (DDM) is capable for the transceiver

Connector Code

The transceiver connector code

Vendor OUI

The vendor organizationally unique identifier (OUI)

Manufacture Date

The manufacture date of the transceiver

Media

The intended media for the transceiver to send and receive

Serial Number

The serial number of the transceiver

Part Number

The part number of the transceiver

Optical Compliance

The optical compliance code of the transceiver

Link Length Support

The supported link length of the transceiver

Traffic Statistics

Octets input/output

The total number of octets received and transmitted on the port

Packets input/output

The number of packets, delivered by this sublayer to a higher (sub) layer, which were not addressed to a multicast or broadcast address at this sublayer. The total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent.

Errors Input/Output

For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol.

For packet-oriented interfaces, the number of outbound packets that could not be transmitted because of errors. For character-oriented or fixed-length interfaces, the number of outbound transmission units that could not be transmitted because of errors.

Port Statistics

Unicast Packets Input/Output

The number of packets, delivered by this sublayer to a higher (sub) layer, which were not addressed to a multicast or broadcast address at this sublayer. The total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent.

Multicast Packets Input/Output

The number of packets, delivered by this sublayer to a higher (sub) layer, which were not addressed to a unicast or broadcast address at this sublayer. The total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a unicast or broadcast address at this sublayer, including those that were discarded or not sent

Broadcast Packets Input/Output

The number of packets, delivered by this sublayer to a higher (sub) layer, which were not addressed to a unicast or multicast address at this sublayer. The total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a unicast or multicast address at this sublayer, including those that were discarded or not sent.

Discards Input/Output

The number of inbound/outbound packets chosen to be discarded to possibly free up buffer space

Unknown Proto Discards Input/Output

For packet-oriented interfaces, the number of packets received via the interface that were discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received via the interface that were discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter will always be 0. Unknown proto discards do not show up in the packet counts
