802.1q fast ether channel trunk Packet size

[ldodd]

does anyone know what the maximum packet size for a fast etherchannel trunk packet would be ?

i am planning to combine 2 100 meg wireless site to site links connected to a 2924m xl switch or a 3512 switch the wireless bridge i am using has a mx of 1544

The 802.1Q tag is four bytes long. That will result in 1522 bytes in a maximum-size frame.

so, 1522 for 802.1q tag

how much for etherchannel?

how much for trunk

For an etherchannel no data is added, because it usualy is based on load sharing per session (source / destination mac)
