256 Using FlexAddress Plus
If a chassis currently has FA activated, FA does not need to be deactivated in
order to add FA+.
In this case, the MAC address allocations are applied as follows:
• The MAC addresses of scheme 1 are allocated from FA of the feature card
1.0. There is no change in the previous WWN/MAC configuration.
• The additional MAC addresses of scheme 2 are allocated from the scheme
2 addresses of FA+.
MAC Address Allocation Example
Assume that, the starting address of MACs in FA is 00:FA:AE:58:59:2B, the
starting address of the MACs in scheme 2 of FA+ is 00:FB:AE:58:59:FB. The
server is in slot 1, the network configuration for the server is:
• 1 MAC for iDRAC
• 8 MACs for fabric A
• 4 MACs for fabric B
• 4 MACs for fabric C
Since fabric A needs four more MAC addresses than scheme 1 can provide,
the first 4 MACs are allocated from FA based on scheme 1 with two MACs for
port 1, and two MACs for port 2. The additional four MACs are allocated
from FA+ based on scheme 2, with two MACs for port 1 and two MACs for
port 2. The MAC addresses allocation for iDRAC for fabric B and C are from
FA based on scheme 1.
The starting address of fabric A port 1 from FA+ is 00:23:AE:58:59:FE,
because the first 3 MACs are reserved for iDRAC. Thus the chassis-assigned
MAC addresses for the server are:
iDRAC 00:FA:AE:58:59:2B (from FA)
Fabric A port 1: 00:FA:AE:58:59:2C(from FA)
00:FA:AE:58:59:2D (from FA)
00:FB:AE:58:59:FE (from FA+)
00:FB:AE:58:59:FF (from FA+)
