should be applied to the port channel interface. Although the Cisco IOS Software allows conﬁguration on physical

interfaces, the conﬁguration will not be propagated to the port channel bundle. If the interfaces within the bundle

are not identical, the channel will not form.

CatOS supports a maximum of 128 EtherChannel groups and the Cisco IOS Software supports a maximum of 64

EtherChannel groups.

EtherChannel Negotiation

Cisco IOS and CatOS EtherChannels support both PAgP and LACP, which allows for automatic creation of port

channels with other devices. PAgP is a Cisco prioprietary protocol for channel negotiation and LACP is a standard

for channel negotiation (IEEE 802.3ad). The negotiation modes of both protocols are nearly identical. Note that the

negotiation keywords are the same for both CatOS and Cisco IOS Software. For more detail on PAgP and LACP

conﬁguration, refer to the following conﬁguration guides:

PAgP Conﬁguration Example:

CatOS Cisco IOS Software

set port channel 3/1-8 1 desirable interface range gigabit 3/1 – 8

interface port-channel 1

switchport trunk encapsulation dot1q

no shut

CatOS Cisco IOS Software

set channelprotocol pagp

set port channel 3/1-8 1 desirable
