port

Specifies the port number.

credits

Specifies the number of credits to be allocated to the specified port. The specified credit

allocation takes effect when the E_Port comes online. This operand is required with the

--enable option. The minimum credit allocation is 5 and the maximum is 40 for Gen5

platform (16Gbps-capable blades). For ICL ports of Gen5 platform, the valid range is from 5

through 16. For Gen 6 platform, the credit allocation is allowed in the range between 5 to

160 for both ICL ports and normal ISL and EX Port links. In Gen 6 platform, if the specified

credit allocation is less than the default allocation, the default allocation scheme is enforced

(in Gen 6 platform, 32 Gbps links are reserved 20 credits per VC). The configured credits

will be allocated for each of the medium virtual channels (VCs) for the non-QoS ports. For

QoS ports, after sharing, both the medium and high VCs will have the configured credits

allocated.
