Pairing odd physical type interfaces for ips

In the 4250-sx, there is a copper gigabit interface (ge_0/0) and a fiber gigabit interface (ge_1/0). Can these interfaces be paired together to do blocking or do they have to be the same physical type.

What are the disadvantages, if any, of pairing odd physical type interfaces?

Re: Pairing odd physical type interfaces for ips

Pairing of copper and fiber interfaces is not supported.

We have not tested this configuration and do not know what issues might develop from that combination.

Here is the list of supported inline interface pairs:

Alternatives:

1) Purchase a second SX interface from Cisco so you can pair the 2 SX interfaces.

2) Use InLine Vlan Pairs which pairs 2 vlans on a single interface instead of using 2 interfaces. You can then create inline vlan pairs on the SX card, and can even created inline vlan pairs on the TX interface ofthe motherboard at the same time.
