hold-time
Syntax hold-time hold-time
no hold-time
Context config>port>aps
Description
This command specifies how much time can pass, in 100s of milliseconds, without receiving an
advertise packet from the neighbor before the multi-chassis signaling link is considered not
operational.
The hold-time is usually 3 times the value of the advertise-interval . The value of the advertise-
interval is valid only for a multi-chassis APS as indicated by the value of neighbor IP address if it is
not set to 0.0.0.0.
Parameters hold-time — Specifies how long to wait for an APS advertisement packet before the peer in a Multi-
Chassis APS group is considered operationally down.
Values 10 — 650
neighbor
Syntax neighbor ip-address
no neighbor
Context config>port>aps
Description This command specifies the neighbor's IP address only on a multi-chassis APS where the working
and protect circuits are configured on different routers. When the value the neighbor IP address is set
to 0.0.0.0, this implies that the APS group is configured as a single-chassis APS group.
The route to the neighbor must not traverse the multi-chassis APS member (working or protect)
circuits. It is recommended that the neighbor IP address configured is on a shared network between
the routers that own the working and protect circuits.
By default no neighbor address is configured and both the working and protect circuits should be
configured on the same router (i.e., single-chassis APS). APS is assumed to be configured wholly on
a single chassis.
Parameters ip-address — Specifies the neighbor's IP address only on a multi-chassis APS where the working and
protect circuits are configured on different routers. The node should be connected with a direct
interface to ensure optimum fail-over time.
Values ipv4-address: a.b.c.d
ipv6-address: x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x: [0 — FFFF]H
d: [0 — 255]D
