NRP Redundancy
Verifying NRP Redundancy
To verify NRP redundancy, use the show redundancy EXEC command on the NRP:
Router# show redundancy
Primary NRP in slot 2, system configured non redundant
User EHSA configuration (by CLI config):
slave-console = off
keepalive = on
config-sync modes:
standard = on
start-up = on
boot-var = on
config-reg = on
NSP EHSA configuration (via pam-mbox):
redundancy = off
preferred (slot 2) = yes
Debug EHSA Information:
NRP specific information:
Backplane resets = 0
NSP mastership changes = 0
print_pambox_config_buff: pmb_configG values:
valid = 1
magic = 0xEBDDBE1 (expected 0xEBDDBE1)
nmacaddrs = 1
run_redundant = 0x0
preferred_master = 0x1
macaddr[0][0] = 0010.7b79.af93
macaddr[1][0] = 0000.0000.0000
EHSA pins:
peer present = 0
peer state = SANTA_EHSA_SECONDARY
crash status: this-nrp=NO_CRASH(1) peer-nrp=NO_CRASH(1)
EHSA related MAC addresses:
peer bpe mac-addr = 0010.7b79.af97
my bpe mac-addr = 0010.7b79.af93
Erasing Startup Configurations on Redundant NRPs
To erase the startup configuration on redundant NRPs, complete the following steps beginning in EXEC
mode:
Note If you erase the startup configuration on the primary NRP only, and the primary and secondary NRPs
reverse roles, the new primary NRP will use the old startup configuration.
Command Purpose
Step1
Router# erase nvram:
Erases the primary NRP’s startup configuration.
Step2
Router# erase sec-nvram:
Erases the secondary NRP’s startup configuration.
