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. 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 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
Availability"
Channel 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 Cisco MDS 9000 Family NX-OS Interfaces Configuration Guide for more information). The
maximum number of Fibre Channel ports that can be put into a Fibre Channel PortChannel is 16 (see
