Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 743
Configured Mode network: the port is configured for transport network use
access: the port is configured for service access
Encap Type The encapsulation type for the channel group (atm, cem,
ipcp, ppp-auto)
Admin MTU The configured MTU
Oper MTU The negotiated size of the largest packet that can be sent
on the port or channel specified in octets
Scramble Indicates whether payload scrambling is enabled on
channel groups (only applicable if encap type is atm)
CRC Indicates the precision of the cyclic redundancy check:
16 — a 16-bit CRC calculation
32 — a 32-bit CRC calculation; 32-bit CRC increases the
error detection ability, but it also adds some performance
overhead
Physical Link Yes: a physical link is present
No: a physical link is not present
Idle Cycle Flags The value transmitted by the DS0, DS1, or E1 interface
during idle cycles
FEAC Loop Respond Indicates whether the associated DS3 interface can
respond to remote loop signals
Cfg Alarm The alarms that have alarm reporting enabled
Alarm Status The current alarm state (for example, stray, malformed,
packet loss, overrun, underrun, remote packet loss,
remote fault, or remote RDI)
Framing The DS3 framing mode
Clock Source loop-timed: the link recovers the clock from the received
data stream
node-timed: the link uses the internal clock when
transmitting data
adaptive: clocking is derived from the incoming
pseudowire packets
Port IfIndex The interface’s index number, which reflects its
initialization sequence
