Description
This command configures the number of keepalive intervals that must pass without receiving a
keepalive packet before the link is declared down. It is expected that the nodes at the two endpoints
of the cHDLC link are provisioned with the same values.
Default
3
down-count —
Specifies the number of keep alive intervals that must pass without receiving a keep
alive packet before the link is declared down.
Values

Description
This command configures the encapsulation method used to on the specified port, path, or channel.
This parameter can be set on both access and network ports.
When the
encap-type
is set to ATM the CRC, timeslots, scrambling (if applicable), and idle-cycle-
flags are set to ATM defaults respectively. When the encap-type is changed from ATM, those
parameters are set to their non-ATM defaults.
When the
encap-type
is ATM, ATM sub-layer verification (GR-1248-CORE,
Generic Requirements
for Operations of ATM Network Elements (NEs)
) is automatically enabled. When ATM PLCP cell
mapping is used, the results of this verification include:
• PLCP Severely Errored Framing Seconds
• PLCP Alarm State
• PLCP Unavailable Seconds Counter
When ATM direct cell mapping is used, the result of the verification includes:
• Out of Cell Delineation (OCD) event count. The OCD event count is described in RFC 2515,
Definitions of Managed Objects for ATM Management
. Note that multiple events occurring
within a second will be counted as 1 event for ASAP MDAs as a result of a hardware limit.
