To configure two Alteons as peers to each other
1. From Alteon 1, configure Alteon 2 as a peer and specify its IP address:
2. From Alteon 2, configure Alteon 1 as a peer and specify its IP address:
Note: Port specific parameters, such as which filters are applied and enabled on which ports, are
part of what is pushed by the /oper/slb/sync command. Therefore, if you use the /oper/slb/
sync
command is used, Radware recommends that the hardware configurations and network
connections of all Alteons in the virtual router be identical. This means that each Alteon should be
the same model, have the same line cards in the same slots (if modular), and have the same ports
connected to the same external network devices. Otherwise, unexpected results may occur when
the /oper/slb/sync command attempts to configure a non-existent port or applies an
inappropriate configuration to a port.
You can define whether or not to synchronize certificate repository components by enabling
cfg/
slb/sync/certs
. By default, this option is disabled. When certificate repository synchronization is
enabled, you are required to set a passphrase to be used during the configuration synchronization
for the encryption of private keys (
cfg/slb/sync/passphrs). The same passphrase should be set
manually by the administrator in all VRRP members for private key decryption.
To encrypt or decrypt certificate private keys during configuration synchronization, the same
passphrase must be set at all peer devices.
Synchronizing Active/Active Failover
With VRRP and active-active failover, the primary and secondary Alteons do not require identical
configurations and port topology. Each Alteon can be configured individually with a different port
topology, SLB, and filters. If you would rather force two active-active Alteons to use identical
settings, you can synchronize their configuration using the following command:
>> Main # /cfg/slb/sync
(Select the Synchronization
menu)
>> Config Synchronization # peer 1
(Select a peer)
>> Peer Switch 1 # addr <IP address>
(Assign the Alteon 2 IP address)
>> Peer Switch 1 # enable
(Enable peer Alteon)
>> Main # /cfg/slb/sync
(Select the Synchronization
menu)
>> Config Synchronization # peer 2
(Select a peer)
>> Peer Switch 2 # addr <IP address>
(Assign Alteon 1 IP address)
>> Peer Switch 2 # enable
(Enable peer Alteon)
>> Main # /oper/slb/sync
