OneX support on 4900M

Hello,

I'm designing a network containing two 4900M switches, which need to be linked to eachother using two 10Gb links. Instead of using X2 transceivers (X2-10GB-SR). I want to save costs and use the OneX converter (CVR-X2-SFP10G) with the TwinAx cables (SFP-H10GB-CU5M).

However, our partner tells me the OneX converter is only supported on the WS-X4908-10GE module (which is not part of my design).

I'm not convinced this is true, since the 4900M datasheet and the 10Gb compatibility Matrix do not mention this.

Does anyone have any experience with this kind of setup?

Thanks in advance.

Re: OneX support on 4900M

Hello Antonio,

The 4900M datasheet from Cisco is a bit unclear on this point, but this is supported!

Below are some show commands from my switch running this setup:

switch#show version
Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-IPBASEK9-M), Version 12.2(54)SG, RELEASE SOFTWARE (fc3)
 
System image file is "bootflash:cat4500e-ipbasek9-mz.122-54.SG.bin"

 

cisco WS-C4900M (MPC8548) processor (revision 2) with 524288K bytes of memory.
Processor board ID JAE1435003D

 

switch#show inventory

PID: MIDPLANE          , VID:      , SN: JAE1435003D

NAME: "Linecard(slot 1)", DESCR: "4900M 10GE (X2) with 8 10GE X2 ports"

NAME: "TenGigabitEthernet1/3", DESCR: "SFP-10Gbase-SR"
PID: SFP-10G-SR        , VID: V02  , SN: AGD142960V6

 

switch# show interface Te1/3 status

Port      Name               Status       Vlan       Duplex  Speed Type
Te1/3                        connected    1            full    10G 10GBase-SR
switch#

Notice that both de CVR-X2-SFP10G and the SFTP-10G-SR are installed on interface Te1/3.
