Advanced Console Server & RIM Gateway User Manual 45
 Click Apply. You have selected the failover method however it is not active until you have specified the external
sites to be probed to trigger failover, and set up the failover ports themselves. This is covered in Chapter 5.
Note The ACM5504-5-G-I, IM4004-5 and IM4216-34 can be configured with an active Management LAN/gateway and
with one of the switched Ethernet ports configured for OoB/Failover (ETH 1 on the ACM5504-5-G-I and IM4004-5
or NETOWRK 2 on the IM4216-34). However with the other IM4200, ACM5508-2 and ACM5004-2 models, the
second Ethernet port can be configured as either a gateway port or as an OoB/Failover port, but not both. So
ensure you did not enable the Management LAN function on Network/LAN 2
3.6.4 Aggregating the network ports
By default the console server's Management LAN network ports can only be accessed using SSH tunneling /port
forwarding or by establishing an IPsec VPN tunnel to the console server.
However all the wired network ports on the console servers can be aggregated by being bridged or bonded.
 By default Interface Aggregation is Disabled on the System: IP General Settings menu
 Select Bridge Interfaces or Bond Interfaces
o When bridging is enabled, network traffic is forwarded across all Ethernet ports with no firewall
restrictions. All the Ethernet ports are all transparently connected at the data link layer (layer 2) so they do
retain their unique MAC addresses
o With bonding he network traffic is carried between the ports but they present with one MAC address
o Both modes remove all the Management LAN Interface and Out-of-Band/Failover Interface functions
and disable the DHCP Server
