Configuring Trunk Port Redundancy
Example of automatic redundancy configuration
[in OC3-ATM/{ any-shelf any-slot 0 }]
name = ""
spare-physical-address = { any-shelf any-slot 0 }
sparing-mode = inactive
Example of automatic redundancy configuration
To use automatic trunk port redundancy, you modify the profile of a primary trunk port to
specify a spare trunk port and enable automatic redundancy. For example, the following
commands specify that the first port in slot 17 is a primary trunk port, and the first trunk port in
slot 18 is its spare:
admin> read oc3-atm {1 trunk-module-1 1}
OC3-ATM/{ shelf-1 trunk-module-1 1 } read
admin> set spare-physical-address shelf = 1
admin> set spare-physical-address slot = 18
admin> set spare-physical-address item-number = 1
admin> set sparing-mode = automatic
admin> write
OC3-ATM/{ shelf-1 trunk-module-1 1 } written
Note that Spare-Physical-Address is a complex field. You can set its value by specifying the
parameter name and the relevant subfield on the Set command line, as shown immediately
above, or by listing the complex field and then setting its values directly. For example:
admin> read oc3-atm {1 trunk-module-1 1}
OC3-ATM/{ shelf-1 trunk-module-1 1 } read
admin> list spare-physical-address
[in OC3-ATM/{ shelf-1 trunk-module-2 1 }:spare-physical-address]
shelf = any-shelf
slot = any-slot
item-number = 0
admin> set shelf = 1
admin> set slot = 18
admin> set item-number = 1
admin> list ..
Parameter
Specifies
Spare-Physical-Address
Physical address of the trunk port to be used as a spare for this
port. The value is a complex field that specifies the shelf-number,
slot-number, and item (port) number of the spare port.
Sparing-Mode
If set to
inactive
(the default), the sparing function is disabled.
The
automatic
setting means the active port changes from
primary to the spare port and back, based on the line status of the
active port. Setting this parameter to
manual
inactivates the
primary trunk port and activates the spare trunk port. Setting it
back to
inactive
brings down the spare and reactivates the
primary port.
