Ethernet PortChannels and Fibre Channel PortChannels

Ethernet PortChannels offer link redundancy between the Cisco MDS 9000 Family switch's Gigabit
Ethernet ports and the connecting Ethernet switch. On the other hand, Fibre Channel PortChannels also
offer (E)ISL link redundancy between Fibre Channel switches. FCIP is an (E)ISL link and is only
applicable for a Fibre Channel PortChannel. Beneath the FCIP level, an FCIP link can run on top of an
Ethernet PortChannel or just on one Gigabit Ethernet port. This link is totally transparent to the Fibre
Channel layer.
An Ethernet PortChannel restriction only allows two contiguous IPS ports, such as ports 1–2 or 3–4, to
be combined in one Ethernet PortChannel (see the
section on page
PortChannel (to which FCIP link can be a part of) does not have a restriction on which (E)ISL links can
be combined in a Fibre Channel PortChannel as long as it passes the compatibility check (see the
"Compatibility Check" section on page
be put into a Fibre Channel PortChannel is 16 (see
