Which two conditions must exist in order to add a new link to an aggregation?
A.
The new link appears in the output of dladm show-phys.
B.
The new link may already support an active interface.
C.
The LACP policy must be set to L4.
D.
The link may currently be in any state.
E.
The new link has the same MAC address as the existing links.
Explanation:
A:
Note:
Use dladm show-phys to obtain information about the system’s datalinks in relation to the physical NICs with
which they are associated. Used without any options, the command displays information similar to the following:
# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
net0 Ethernet up 100Mb full e1000g0
net1 Ethernet down 0Mb — nge0
net2 Ethernet up 100Mb full bge0
net3 Infiniband — 0Mb — ibd0
* Your link aggregation configuration is bound by the following requirements:
/You must use the dladm command to configure aggregations.
/ (not B) An interface that has been created cannot become a member of an aggregation.
/All interfaces in the aggregation must run at the same speed and in full-duplex mode.
/ (not E) You must set the value for MAC addresses to “true” in the EEPROM parameter local-mac-address?
