Object References Select an entry and click Object References to open a screen that shows which settings use
the entry.
# This field is a sequential value, and it is not associated with any interface.
Status This icon is lit when the entry is active and dimmed when the entry is inactive.
Name This field displays the name of the LAG interface.
Mode Mode refers to whether the LAG is acting as follows:
• active-backup where only one slave in the LAG interface is active and another slave
becomes active only if the active slave fails.
• 802.3ad (IEEE 802.3ad Dynamic link aggregation) where Link Aggregation Control
Protocol (LACP) negotiates automatic combining of links and balances the traffic load
across the LAG link by sending LACP packets to the directly connected device that also
implements LACP. The slaves must have the same speed and duplex settings.
• balance-alb (adaptive load balancing) where traffic is distributed according to the
current load on each slave by ARP negotiation. Incoming traffic is received by the
current slave. If the receiving slave fails, another slave takes over the MAC address of
the failed receiving slave.
IP Address This field displays the current IP address of the LAG interface. If the IP address is 0.0.0.0, the
interface does not have an IP address yet.
This screen also shows whether the IP address is a static IP address (STATIC) or dynamically
assigned (DHCP). IP addresses are always static in virtual interfaces.
Mask This field displays the interface’s subnet mask in dot decimal notation.
Member This field displays the physical Ethernet interface that is a member of this LAG. Members do
not have an IP Address and in some cases share the same MAC address.
PVID This field indicates the interface’s PVID.
