ipcp — Ingress frames are encapsulated according to the IP Control Protocol. When ipcp encapsulation is
specified, the PPP IP Control Protocol will be activated and only packets that comply with IPCP encap-
sulation are processed; others are silently discarded.
ppp-auto — (Network mode) Enables PPP on the associated port/channel. The activation of ipcp and
mplscp is automatically enabled depending on the protocol configuration. This encap type is only valid
on ports/channels in network mode.
frame-relay — Enables frame relay on the associated port/channel.
wan-mirror — The port is used for mirroring of frame-relay and POS ports. On these ports, no link man-
agement protocol will run.
cisco-hdlc — Monitors line status on a serial interface by exchanging keepalive request messages with peer
network devices.
cem — On circuit emulation CMAs and MDAs, only the cem encap-type is supported. All other values are
blocked with an appropriate warning. The cem encap-type is not supported on other CMAs and MDAs
and are blocked with an appropriate warning.
feac-loop-respond
Syntax [no] feac-loop-respond
Context config>port>tdm>ds3
config>port>tdm>e3
Description This command enables the associated DS-3 interface to respond to remote loop signals.
The DS-3 far-end alarm and control (FEAC) signal is used to send alarm or status information from the far-
end terminal back to the local terminal. DS-3 loopbacks at the far-end terminal from the local terminal are
initiated.
The no form of this command prevents the associated DS-3/E-3 interface from responding to remote loop
signals.
Default no feac-loop-respond
framing (DS-1)
Syntax framing {esf | sf | unframed-ds1}
Context config>port>>tdm>ds1
Description This command specifies the DS-1 framing to be used with the associated channel.
Default DS1: esf
Parameters esf — Configures the DS-1 port for extended super frame framing.
sf — Configures the DS-1 port for super frame framing.
