Hosts - Avocent Cyclades ACS Command Reference Manual

To configure bonding:
1. Enable / disable bonding.
cli> config network hostsettings bonding enabled [no|yes]
NOTE: This parameter is disregarded when DHCP is enabled.
2. Configure the interval, in milliseconds, to verify if the primary interface is still active.
bonding> miimon <positive_integer_value>
3. Configure the time, in milliseconds, that the system waits to reactivate the primary interface
after it has been detected as up.
bonding> updelay <positive integer value>
4. Optionally, confirm values.
bonding> show
5. Activate and save your configuration.
6. Check the bonding configuration from the Linux shell.
# ifconfig
After the failover is enabled, the bonded Ethernet interfaces are referred to as bond0. The eth0 and
eth1 represent the two physical interfaces. To check which physical interface is the primary and
which is the failover, look for the status NOARP. The interface which has the NOARP status
(eth1by default) is the failover. While eth1 is in active and standby mode, eth0 is sending and
receiving packets.
If you have IP filtering rules set before bonding is activated, the interface reference in the firewall
IP filtering is set to eth0. Change the interface to bond0 in order to reference the bonded interface.
For example, there is a rule to drop the SSH packets to access the ACS console server box with
no bonding.
# iptables -A INPUT -p tcp –dport 22 -i eth0 -j REJECT
If you activate bonding, change the rule to reference the bonded interface.
# iptables -A INPUT -p tcp –dport 22 -i bond0 -j REJECT

Hosts

To configure hosts:
1. Add a host name with IP address.
cli>config network hosttable add hostip <n.n.n.n> name [hostname]
You may repeat this step as many times as necessary.
2. Activate and save your configuration.
