On the E-Series TeraScale, you can add up to 16 interfaces to a Port Channel; E-
Series ExaScale can add up to 64. You can have eight interfaces per Port Channel
on the C-Series and S-Series. The interfaces can be located on different line cards
but must be the same physical type and speed (for example, all 1-Gigabit Ethernet
interfaces). However, you can combine 100/1000 interfaces and GE interfaces in
the same Port Channel.
If the Port Channel contains a mix of interfaces with 100 Mb/s speed and 1000
Mb/s speed, the software disables those interfaces whose speed does not match
the speed of the first interface configured and enabled in the Port Channel. If that
first interface goes down, the Port Channel does not change its designated speed;
disable and re-enable the Port Channel or change the order of the channel
members configuration to change the designated speed. If the Port Channel
contains a mix of interfaces with 100 Mb/s speed and 1000 Mb/s speed, the
software disables those interfaces whose speed does not match the speed of the
first interface configured and enabled in the Port Channel. If that first interface
goes down, the Port Channel does not change its designated speed; disable and
re-enable the Port Channel or change the order of the channel members
configuration to change the designated speed. For more information about Port
Channels, refer to the Dell Networking OS Configuration Guide.
