Link Aggregation??

[Dennis L W Thury]

Is there any experience with configuring and/or operating Tru64 Unix with Link Aggregation? I've had some bad experiences with Microsoft's "Teaming", and need some "testimonials" that this aggregation really works!!

Anything I need to particularly careful about?

Any advise/recommendations>

Thanks,
Denny

Hi,

for an overview look here:
http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51B_HTML/ARH9CDTE/NTCHPXXX.HTM#anch_0041
for configuration look here:
http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51B_HTML/ARH9CDTE/NTCHPXXX.HTM#anch_0169

I haven't used it myself but I think, it works fine. I assumed you have V5.1B. For a different version look here:

go to system and network management

The LAG support works correctly if using a switch supporting this mode.

Be sure you are using the supported network controllers (e.g. DE60x, Gigabit) to form lag support.

Link Aggregation has been successfully tested with the following switches:

Foundry FastIron II
Extreme networks Summit 7i
Alteon ACE180
Cisco 6509, 6513, 3524XL
3COM 4900 SX

Note: Interoperability with manual configuration only. IEEE 802.3ad LACP and Cisco's Port Aggregation Protocol (PAgP) are not supported.

Thanks for the feedback. We have the Cisco 6509 Switches so we should be all set. However, when I talk to my Networker folks about this link aggregation, I get kinda of a blank look from them!??! I don't think they know what "lag" means!! I hope/trust, that if/when we start looking through the CISCO documentation, what needs to be done will be fairly straight forward!!??!!

lag is not a "HP/Compaq" feature, so I wonder why a network guru doesn't know it.
lag means "link aggregation" maybe there are some other vendor specific words for it.

Hi,

under HP-UX it is called apa/auto port aggregation.
