I'm starting to use the 4800 series more in my job now but previously my knowledge of XRN has applied to 4500 and 5500 switches and it's never caused me any issues.
I note that the stack configuration is different on the 4800, but what is strange is that if I try to type anything to do with IRF, I see nothing at all. If I simply do "?" at the command line (in system view), I see nothing about IRF or XRN. I also don't see anything in the web interface.
Here is a dis ver from one unit:

As can be seen, both units are fitted with 2 x 10GE CX4 modules and are showing as active for both units on the web interface. This switch is a remote device so I can't look at the back panel.
Perhaps I'm just missing something obvious? Until now the only 4800 installs I have done have been single units so no stacking. However I have looked at the documenation and from system view I should be able to do for example "irf member..."
I also note however that it does mention that before configuring the units that you have to bind the physical stack port to a logical one....but I can't see in the documentation how to do this.
It also says that simply powering off the units, cabling the CX4 modules and rebooting should automatically stack the units, but this has been tried and didn't work.
Another thing...with XRN on the 5500 there were 3 pre-reqs:
- Same software version
- Same system name
- Same switch family
I don't see anything about sysname for the 4800, so is this still a requirement?
Would certainly appreciate any assistance.
Thanks in advance.
