4 – EVIC Configuration and Monitoring Features
D000003-006 Rev. A 4-25
Q
Indicates whether the Ethernet link is up or down (viewable only).
LACP Enabled
Indicates whether the Link Aggregation Control Protocol (LACP , IEEE
802.3ad ) is enabled on the port. If LACP is enabled (i.e. LACP Enabled =
Yes) then the current aggregation number is selected automatically and the
actor key (1- 65535) should be specified (see 'actor key' definition later in this
section). If LACP is disabled (i.e., LACP Enabled = No), then the aggregation
index should be specified (see Manual Agg# definition below). Disabling
LACP is also known as manual mode.
Current Agg #
This field describes the aggregation where a port is currently located. If two
rows contain the same value, they are part of the same aggregation.
Manual Agg #
If LACP is disabled (i.e., Lacp Enabled = No), then the user sets this field to
describe which ports should be in the same aggregation.
LACP State
Indicates the LACP state (OK, N/A, or Fail). This field is view only.
Failover
The minimum number of links that must be remaining in an aggregation in
order for aggregation failover to occur. When failover occurs for a port, traffic
that would normally be directed over the link that went down is redistributed
across the remaining links in the aggregation. Ports that are running in failover
mode do not count towards the number of remaining links.
For an EVIC, this value should be 0 or 1.
If the value is 0, failover is disabled. In this case when a link goes down, all
viPorts using that Ethernet port will receive a 'link down' event regardless of
the state of other links in the aggregation. This causes the viPort to failover
to the Secondary definition (this could possibly be a different EVIC).
If the value is 1 and a link goes down, there must be 1 or more remaining
links in the aggregation for the viPort to consider the port to still be up and
can continue to send data.
Actor Key
If LACP is enabled, then the user inputs an identical Actor Key in each row
that is to be part of the same aggregation. If LACP is disabled, this field is
greyed out. Valid values are 1-65535.
