Connection problems between Cisco and Alcatel

[jason.dauriat]

Hi,

We encouter problems flow between two switches at work. The first is a Cisco 3550 and the second is an Alcatel 6400.

For the tests, I connected a PC on each switches on acces port. The 2 switches are connected by a trunk port (the 24th for each switches).

I forgot to tell that the 2 switches are on the same vlan (5).

I made some tests and it takes about 2 minutes to transfer 45mo from one pc to the other one.

I can give a part of the configuration :

Alcatel :

5. switchport mode trunk
   
6. power inline never
   
7. speed 100
   
8. duplex full
   
9. spanning-tree portfast
   

If someone could help me, it would be very nice.

Thank you and sorry for my english

Hi,

can you try with auto negotiation of speed and duplex mode on the Cisco side ?

Thank you for your answer but it didn't help. It still took 124 secs for the transfer.

I tried your solution with an access port between the 2 switches, the transfer was a bit faster (~~ 100 secs) but it's still not enough.
