Configuring an Extended Fabric Connection Long Distance Configuration Note: Only active GBICs should be used when using HP Extended Fabric. Note: Trunking is not supported with LE, L1, and L2 modes. The long distance extended fabrics configuration needs to be set only once for each fabric at the edge switch E-port. The configuration should be between any same series switch. Long distance ports consume more buffers than regular ISL ports, which means that a long distance port could disable other ports in the same quad due to lack of buffers. Refer to the "Long Distance Port Matrix" on page 27 for buffer credit information. 20 Extended Fabric Version 3.1.x/4.1.x User Guide

Long Distance Configuration
Note:
Only active GBICs should be used when using HP Extended Fabric.
Note:
Trunking is not supported with LE, L1, and L2 modes.
The long distance extended fabrics configuration needs to be set only once for
each fabric at the edge switch E-port. The configuration should be between any
same series switch. Long distance ports consume more buffers than regular ISL
ports, which means that a long distance port could disable other ports in the same
quad due to lack of buffers. Refer to the “
Long Distance Port Matrix
” on page 27
for buffer credit information.
