How replacing port blades affects EX_Port configuration
If you replace an FR4-18i blade with an 8-Gbps port blade or FX8-24 blade, the EX_Port
configuration remains the same for the first 16 ports on the 8-Gbps port blade (and for the first 12
FC ports on the FX8-24 blade). For all other ports on the blade, the EX_Port configuration is
cleared. No ports are persistently disabled.
If you replace an 8-Gbps port blade or FX8-24 blade with an FR4-18i blade, the EX_Port
configuration remains the same for all ports on the FR4-18i blade. All ports are persistently
disabled.
If you replace an 8-Gbps port blade with an FX8-24 blade, the EX_Port configuration remains the
same for the first 12 FC ports on the FX8-24 blade.
If you replace an 8-Gbps port blade or FX8-24 blade with another 8-Gbps port blade, the EX_Port
configuration remains the same.
Displaying the range of output ports connected to xlate domains
The edge fabric detects only one front domain from an FC router connected through multiple output
ports. The output port of the front domain is not fixed to 0; the values can be in a range of 129–
255. The range of the output ports connected to the xlate domain is 1–128. This range enables the
front domain to connect to 127 remote xlate domains.
1. Log in to a switch in the edge fabric.
2. Enter the lsDbShow command on the edge fabric.
In the lsDbShow output, ports in the range of 129–255 are the output ports on the front
domain.
The following example shows the range of output ports.
linkCnt = 2, flags = 0x0
LinkId = 53, out port = 1, rem port = 35, cost = 500, costCnt = 0, type = 1
LinkId = 57, out port = 129, rem port = 18, cost = 500, costCnt = 0, type = 1
The following example also shows the use of the lsDbShow display on the edge fabric. The front
domain, domain 3, has two links representing two EX_Port connections with output ports 129
and 132.
Domain = 3, Link State Database Entry pointer = 0x100bbcc0
………
linkCnt = 4, flags = 0x0
LinkId = 199, out port = 129, rem port = 2, cost = 10000, costCnt = 0, type = 1
LinkId = 199, out port = 132, rem port = 3, cost = 10000, costCnt = 0, type = 1
LinkId = 2, out port = 1, rem port = 2, cost = 10000, costCnt = 0, type = 1
LinkId = 1, out port = 32, rem port = 2, cost = 10000, costCnt = 0, type = 1
