[Archive] Hostnames and SNMP Names Cannot be Different on Master and Slave Devices for HA

0

0

Article ID: KB5409 KB Last Updated: 22 Jul 2010Version: 3.0
Summary:
Hostnames and SNMP Names Cannot be Different on Master and Slave Devices for HA
Symptoms:
Pair of NetScreens running HA
HA checksum is different between local and remote
Different hostname and SNMP name for each device
inconsistent configurations

Solution:

Compare the master and slave configuration files to see if there are any differences between the two.  Some typical mistakes administrators make include:

  1. Using different hostnames for master and slave
  2. Using different SNMP names for master and slave
  3. Using a different syslog server IP address on the master and slave

If the hostname or SNMP names are different, this will cause inconsistent configuration messages.  The configuration consistencies are checked once every hour on the NetScreen.  To eliminate these error messages, synchronize the configurations. 

Here is the problem or goal:

  • inconsistent configurations

Problem Environment:

  • Pair of NetScreens running HA
  • HA checksum is different between local and remote
  • Different hostname and SNMP name for each device
