Field Description
CoS queue number and its associated user-configured forwarding class name.
Displayed with the statistics option.
• Queued packets—Number of queued packets.
• Transmitted packets—Number of transmitted packets.
• Dropped packets—Number of packets dropped by the ASIC's RED mechanism.
Information about the physical media:
• Line protocol—eia530, eia530a, rs232, rs449, v.35, or x.21..
• Resync history—Information about resynchronization events:
• Sync loss count—Number of times the synchronization was lost.
• Data signal—(X.21 and V.35) Information about the data signal:
• Rx Clock—Receive clock status: OK (DTE is receiving the receive clock
signal) or Not detected (receive clock signal is not being received).
• Control signals—Information about modem control signals:
• Local mode:DCE (data communication equipment) or DTE (data terminal
equipment)
• To DCE—Control signals that the Serial PIC sent to the DCE: DTR (Data
Terminal Ready:up or down) or RTS (Request To Send: up or down.)
• From DC—Control signals that the Serial PIC received from the DCE: CTS
(Clear To Send: up or down), DCD (Data Carrier Detect: up or down), DSR
(Data Set Ready: up or down), or TM (Test Mode: up or down).
• Clocking mode—Clocking used for the transmit clock:
• dte—Transmit clock is generated by DTE.
• dce—Transmit clock is generated by the DCE and is looped back as the
transmit clock.
• loop-timed—Receive clock from the DCE is looped back as the transmit
clock.
• Clock rate—Rate, in megahertz (MHz), at which the clock is configured.
• Loopback—Configured loopback mode for the interface: dce-remote, dce-local,
liu, local, or none.
• Tx clock—Clocking phase of the transmit clock: invert (transmit clock polarity
is inverted) or non-invert (transmit clock polarity is not inverted).
• Line encoding—Type of line encoding used: nrz (nonreturn to zero) or nrzi
(return to zero inverted).
Information about the configuration of the Packet Forwarding Engine:
• Destination slot—FPC slot number.
• PLP byte—Packet Level Protocol byte.
