Does 10M ethernet port support Trunk?

[wangyanan]

Hi,

Does 10M ethernet port support Trunk,

for example 17xx, 26xx and 25xx router?

[Gilles Dufour]

2600

--------

For the default ethernet port (not the network modules).

VLAN: No hardware support for Cisco ISL, IEEE 802.1q is tested and supported as of 12.2(2)T (may work in earlier versions).

NM-16ESW and NM-32ESW supports 802.1Q

2500 -> not supported

1700 -> don't think so but it might have changed.

Hi Dufour,

Could you please tell me the model of the cheapest routers

that support 10M trunk?

Any model of 25xx doesn't support 10M trunk with its 10M ethernet port?

thanks

The 2500 series router do not support trunk on its ethernet ports.

As previously written, the smallest to be able to do that will be the 2600 router.

Do you have the router already or are you planning to purchase one? The new 1721 model has a 100Mb port and supports dot1q with just the IP feature set. The 2600 models with 10Mb ports (2610, 2611) support dot1q but only with the IP+ feature set.
