Chapter5 Redundancy and SONET APS Configuration
NRP Redundancy
Note Make sure the DHCP server is properly set up with appropriate dynamic and static pools of IP addresses.
Example
In the following example, the NSP network management interface is configured for DHCP IP address
acquisition. This allows you to boot redundant NSPs from a network server.
!
redundancy
main-cpu
auto-sync standard
!
interface ethernet0/0/0
ip address negotiated

Verifying Booting Redundant NSPs from a Network Server
To verify that the NSPs are prepared for netbooting, use the more sec-nvram:startup-config EXEC
command. The presence of the correct commands in the secondary startup configuration confirms that
both NSPs are configured properly.
NRP Redundancy
For two NRPs to act as a redundant pair, they must be installed in one the following slot pairs:
• 1 and 2
• 3 and 4
• 5 and 6
• 7 and 8
Configuring Redundant NRPs
To configure NRP redundancy, complete the following steps, beginning in global configuration mode:
Example
In the following example, the NRPs in slots 1 and 2 are configured as a redundant pair.
!
redundancy
associate slot 1 2
main-cpu
auto-sync standard
Command Purpose
Step1
Switch(config)# redundancy
Enters the redundancy configuration submode.
Step2
Switch(config-r)# associate slot slot [slot]
Configures the two slots as a redundant pair. You need
specify only the first slot of the redundant pair. The second
slot is assumed to be the adjacent slot.
