When the Gigabit Ethernet interface of the VRRP master fails, the iSCSI session is terminated. The host
then reconnects to the target and the session comes up because the second Gigabit Ethernet interface has
taken over the virtual IP address as the new master.

Ethernet PortChannel-Based High Availability

All iSCSI data traffic for one iSCSI link is carried on one TCP connection. Consequently, the aggregated
Note
bandwidth is 1 Gbps for that iSCSI link.
