ancp
Syntax ancp {subscriber sub-ident-string | ancp-string ancp-string} loopback [count count] [tim-
eout seconds] [alarm]
ancp subscriber sub-ident-string loopback [count send-count] [timeout seconds] [alarm]
Context <global>
Description
This command sends an OAM request to the access node. ANCP can be used to send OAM messages
to the access node. The access node must be able to accept these messages and will signal such
support by the capability negotiations. If the operator attempts to send an OAM command to an
access node that does not support such command the operation results in an error.
Parameters
subscriber
ancp-string ancp-string — Specifies an existing ANCP string.
count send-count — Specifies the number of messages the access node will use to test the circuit. If
timeout seconds — Specifies how long the controlling node will wait for a result.
alarm — Specifies that the CLI the result will be retuned to the CLI and a trap will be issued to
loopback — Sendsan OAM loopback test request to the access node
sdp-mtu
Syntax sdp-mtu orig-sdp-id size-inc start-octets end-octets [step step-size] [timeout seconds]
[interval seconds]
Context <GLOBAL>
Description
Performs MTU Path tests on an SDP to determine the largest path-mtu supported on an SDP.
The size-inc parameter can be used to easily determine the path-mtu of a given SDP-ID. The
forwarding class is assumed to be Best-Effort Out-of-Profile. The message reply is returned with IP/
GRE encapsulation from the far-end 7750 SR. OAM request messages sent within an IP/GRE SDP
must have the 'DF' IP header bit set to 1 to prevent message fragmentation.
To terminate an sdp-mtu in progress, use the CLI break sequence <Ctrl-C>.
7750 SR OS Services Guide
— Specifies an existing subscriber-id. The node will use the ancp-string
sub-ident-string
associated with the provided subscriber-id to identify the circuit.
omitted, the number will be determined by the access node via local policy.
1 — 32
0 — 300
indicate the test finished. If the flag is used through SNMP the results will be available in the
results MIB and after the node sent the trap to indicate the results are ready.
