Each of these modules supports a maximum of six EtherChannels, with up to eight ports in an EtherChannel bundle. Use this table in order to determine which router platforms support FEC as well as 802.1Q trunking features: Router PlatformĬisco 4000-M series (4000-M, 4500-M, 4700-M)Ĭisco 7000 series (RSP 2 7000, RSP 7000CI)ġ An exception to EtherChannel support on Cisco 2600, 3600, and 3700 series routers is when you have installed either the NM-16ESW or NM-36ESW Ethernet Switch Network Module. However, all routers do not support both features. The Catalyst 29/2950 switches do not support Inter-Switch Link Protocol (ISL) trunking due to hardware limitations.Ĭisco routers support EtherChannel and 802.1Q trunking features in Cisco IOS Software Release 12.0(T) and later. The FEC and 802.1Q trunking features are available on the Catalyst L2 fixed configuration switches in Cisco IOS® Software Release 12.0(5.2)WC(1) and later. Prerequisites Requirementsīefore you attempt this configuration, note these requirements: The Requirements section of this document provides a list of routers that support EtherChannel and 802.1Q trunking. But you can use any other router that supports EtherChannel and 802.1Q trunking to get the same results. The Catalyst L2 fixed configuration switches include the 2900/3500XL, 2940, 2950/2955, and 2970 switches.
This document provides a sample configuration for Fast EtherChannel (FEC) and IEEE 802.1Q trunking between Cisco Catalyst Layer 2 (L2) fixed configuration switches and a Cisco router.
