Hi pro,
Could these ports on ES20 and ES+ bundled together?

Hello Huydien,
yes
see
http://www.cisco.com/en/US/docs/routers/7600/install_config/ES20_config_guide/baldovw.html#wp1075778
•Layer 2 switch port (EtherChannel only)
•EtherChannel and Link Aggregate Control Protocol (IEEE 802.3ad)
An EtherChannel bundles individual Ethernet links into a single logical link that provides the aggregate bandwidth of up to eight physical links.The EVC EtherChannel feature provides support for EtherChannels on Ethernet Virtual Connection Services (EVCS) service instances.
comment:
these are ports with a lot of features so if you need a simple L2 etherchannel it would be better to use 2 ports of a simple GE linecard
Hope to help

Hi Giuseppe,
When I configured port-channel btw two port on different linecards, the router notified that cannot do that because qos-type of these line cards are not the same. I issued "no mls qos channel-consistency", but did not know how this impact the network performance.
Under default configuration ports in ES20, we have "mls qos trust", but not in ES+, so what is the alternative command for "trust qos" on ES+?
Thanks!

Hello Huydien,
ES+ looks like to support modular QoS marking instead of port trust see
given this I'm afraid the QoS capabilities mismatch is real, you could implement a policy map to mark all incoming traffic but how to apply it only to a member of the bundle?
Hope to help
