Configuring Interface Details
Under IP Address Configuration > Interface Details, configure VLAN tagging and jumbo
Ethernet frame settings for each port or device (see
Figure 180: Network Page: Interface Details
1. If necessary, click the Show link to show the interface details table.
2. For each device, select the MTU (Maximum Transmission Unit) frame size in the
Jumbo Frame MTU Size drop-down box.

ETERNUS CS800 frame reception is completely dependent on the transmission
algorithm of the Ethernet switch. The bonding mechanism does not balance the
frame reception.
LACP (Mode 4) - This option (Link Aggregation Control Protocol) is based on the
802.3ad IEEE standard for aggregating Ethernet ports. If the bonding algorithm is
set to LACP, the Ethernet switch ports must be configured in a 802.3ad based Link
Aggregation group (LAG) in LACP mode. The ETERNUS CS800 frame reception
and transmission is controlled by the LACP between the bonded ports and the
Ethernet switch ports.
Active Backup (Mode 1) - This option does not require switch configuration but
may not provide the same level of load balancing and performance as other
bonding modes. Only one port in the bond is active at a time. If the active port fails,
another port becomes active to take its place. Because only the MAC address of
the active port is visible to the Ethernet switch, the switch does not require
additional configuration.
