show port info Command Output Descriptions for Ethernet Port Line Card

Field	Description
Port Type	The configured port type. Supported Ethernet port types and data transfer rates are: • Ethernet 10/100 line cards: 10/100 Mbps. • Ethernet 1000 line cards or four-port Quad Gigabit Ethernet line cards: 1000 Mbps. • 1000 Ethernet Dual Media for SPIO line cards: 10/100/1000 Mbps.
Description	The textual description given to the port during software configuration. If no description was configured, (None Set) appears in this field.
Controlled By Card	The slot number and type of the front-installed application card to which this Ethernet line card is mapped.
Redundancy Mode	The redundancy mode configured for this Ethernet line card port. Possible redundancy modes are: • Card: No redundancy will be used. • Port: Port redundancy will be used.
Framing Mode	Ethernet
Redundant With	The slot number and port number of the Ethernet line card that is redundant with this Ethernet line card. If a redundant port is not available, None appears in this field.
Preferred Port	Indicates if this card will assume revertive (auto-recovery) redundancy functionality should this line card be brought back into service after a failure.
Physical ifIndex	The static identification number for the slot/port combination on this Line Card. This ID is used in SNMP traps sent when the link status of the Ethernet port goes up or down.
Administrative State	Enabled indicates that this card has been configured for use via software.
Configured Duplex	Indicates the port’s configured duplex mode. Possible modes are: • Auto: The port auto-detects the appropriate mode (Full- or Half-duplex) for communicating with the network. • Full duplex • Half duplex
Configured Speed	The maximum data rate configured for this port. Possible rates are: • Auto: The port auto-detects the appropriate data rate for communicating on the network. • 10 Mbps • 100 Mbps • 1000 Mbps (supported on Ethernet 1000 Line Cards, Quad Gigabit Ethernet Line Cards, and SPIO Cards.)
Configured Flow Control	Quad Gigabit Ethernet Line Card (QGLC) only: Enabled indicates that Ethernet MAC level flow control has been enabled for this Ethernet port. Note that this is not necessarily the operational state of flow control, as both sides of the connection must agree to flow control during Ethernet negotiation..
MAC Address	The media access control (MAC) address for the port. If Virtual MAC addressing is enabled, the MAC address is followed by (Virtual).
Link State	The port’s link status: Up or Down.
Link Duplex	The actual duplex mode (Full or Half) currently being used for the link.
Link Speed	The actual data rate currently being supported by the port: • 10 Mbps • 100 Mbps • 1000 Mbps
Flow Control	Indicates the current negotiated state of Ethernet MAC level flow control (Enabled or Disabled. Also see Configured Flow Control above).
Link Aggregation Group	QGLC line cards Only: If this port is configured as part of a Link Aggregation Group (LAG), this field indicates the group number to which this port belongs and whether the port is a Master or a Member. If the port is not configured as part of a Link Aggregation Group, None appears in this field.
LAG Toggle Link	QGLC line cards Only: Yes indicates that the QGLC will generate "port link down" and "port link up" events for this LAG port.
LAG Redundancy Mode	QGLC line cards Only: If this port is configured as part of a LAG, this field indicates the Redundancy Mode configured for this Link Aggregation Group: • Standard: Only three of the four LAG ports will failover to the redundant QGLC, so the amount of bandwidth available will be reduced from what was available for the original LAG. • Switched: Used when the Active QGLC LAG ports and its Redundant QGLC are connected to different external switches in the service provider’s network. All four LAG ports will failover to the Redundant QGLC that is connected to the different external switch in provider network.
LAG Hold Time	QGLC line cards Only: If LAG Redundancy Mode is set to Switched, this field indicates the time, in seconds, that will elapse before the system determines that the failover LAG ports must be switched again. This prevents the system from switching rapidly back and forth between the QGLCs during routine maintenance (e.g., when Ethernet cables are being removed and reconnected between QGLCs).
Link Aggregation Master	QGLC line cards Only: If this port is configured as part of a LAG, this field identifies the slot and port number of the QGLC that is the Master of this Link Aggregation Group.
Link Aggregation State	QGLC line cards Only: Indicates the result of the LACP negotiation.
Logical ifIndex	The dynamically assigned identification number for the IP interface bound to this port. This ID is used in SNMP traps sent when the IP interface goes up or down or switches between top and bottom line cards.
Operational State	The operational state and mode of the card, in the format <state,mode>. Possible operational states are Up or Down. Possible operational modes are: • Active: Indicates that the card is an active component that will be used to process subscriber data sessions. • Standby: Indicates that the card is a redundant component. Redundant components will become active through manual configuration or automatically should a failure occur. • Offline: Indicates that the card is installed but is not ready to process subscriber data sessions. This could be due to the fact that the card is not installed correctly (e.g., the card interlock switch is not locked) or that its software processes have been halted.
SFP Module	NOTE: This field appears only for Ethernet line cards that support the use of an SFP module: Ethernet1000 LC, QGLC, XGLC, and SPIO. The displayed type varies based on the vendor of the SFP module. Refer to the show hardware card command for additional information. This field indicates whether or not a small form-factor pluggable (SFP) module is installed on the card and its type. Possible SFP types are: • 1000BASE-T • 1000BASE-SX • 1000BASE-LX • 10GBASE-SR (XGLC only) • 10GBASE LR (XGLC only)
