 |
|
Hi all,
Quick question:
A 2960 (WS-C2960G-48TC-L) with 40 copper Gb ports, going to a few 3548's
that have the 1000Base-T GBIC copper adapter (Part WS-G5483).
The 2960 does auto-MDIX, correct? So I can use straight-thru patch
cables to connect them?
Thanks |

It appears from the 2960 guide (link below) that MDIX is supported and
is enabled by default. I have always elected to use crossovers just
because it is good to have some laying around, and its a safe way to
mitigate risks (I have had many auto-mdix issues related to IBM
Regattas in past lives). I'm sure those issues are fixed now, be we
had to manually disable mdix on all switchports to those servers for
quite sometime due to nobody from either vendor (ibm, cisco) being
able to figure out exactly what was happening on boot that would make
the switchports change polarity.
Anyway, I'd test first, but yes your solution should work. |
