Specifying peer-specific items
Most items of configuration are applied to all peers in a cluster. However, the following items (marked with a
†
on the web interface) must be specified separately on each cluster peer.
Cluster configuration (System > Clustering)
The list of Peer IP addresses (including the peer's own IP address) that make up the cluster has to be
specified on each peer and they must be identical on each peer.
specified on each peer and they must be identical on each peer.
The Cluster name and Cluster pre-shared key have to be specified on each peer and must be identical for
all peers.
all peers.
Ethernet speed (System > Ethernet)
The Ethernet speed is specific to each peer. Each peer may have slightly different requirements for the
connection to their Ethernet switch.
connection to their Ethernet switch.
IP configuration (System > IP)
LAN configuration is specific to each peer.
n
Each peer must have a different IPv4 address and a different IPv6 address.
n
IP gateway configuration is peer-specific. Each peer can use a different gateway.
n
IP routes (also known as static routes) are peer-specific. If these are used, they can be different for each
peer.
peer.
Note that the IP protocol is applied to all peers, because each peer must support the same protocols.
System name (System > Administration)
The System name must be different for each peer in the cluster.
DNS servers and DNS host name (System > DNS)
DNS servers are specific to each peer. Each peer can use a different set of DNS servers.
The System host name and Domain name are specific to each peer.
NTP servers and time zone (System > Time)
The NTP servers are specific to each peer. Each peer may use one or more different NTP servers.
The Time zone is specific to each peer. Each peer may have a different local time.
SNMP (System > SNMP)
SNMP settings are specific to each peer. They can be different for each peer.
Logging (Maintenance > Logging)
The Event Log and Configuration Log on each peer only report activity for that particular Expressway. The
Log level and the list of Remote syslog servers are specific to each peer. We recommend that you set up a
remote syslog server to which the logs of all peers can be sent. This allows you to have a global view of
activity across all peers in the cluster.

The trusted CA certificate, server certificate and certificate revocation lists (CRLs) used by the Expressway
must be uploaded individually per peer.
