I am running 1k of single mode fiber between a 4503 and a 3550. I am trying to run a 2gig etherchannel between the two, using LX GBIC Modules. Does anyone know if there is a distance limitation for this etherchannel other than the cables capabilities?
there is no other limitation to an Etherchannel other than the distance limitations of the physical media. Read below the relevant Q&A from CCO:
Q What are the distance characteristics of Gigabit Ethernet?
A In principle, there is no limit to the size of a Gigabit Ethernet network, in terms of either physical extent or number of nodes. Like Fast Ethernet and the original 10-Mbps Ethernet, Gigabit Ethernet will support a variety of physical media, with different capabilities in terms of maximum link distance. The IEEE 802.3 Higher-Speed Study Group has identified three specific objectives for link distance: A multimode fiber-optic link with a maximum length of 500 meters; a single-mode fiber-optic link with a maximum length of 2 kilometers; and a copper-based link with a maximum length of at least 25 meters. The IEEE is also actively investigating technology that would support link distances of at least 100 meters over Category 5 UTP wiring.
