HP A5120 EI (JE068A) - IRF Configuring

[bgarcias]

Dear Analyst,

I'm trying to configure it and I have had the problem with A5120 EI (JE068A).

====================================================

[sysname]irf-port 1/1

[Sysname-irf-port 1/1]port group interface whateverIwrite
...................................................................^

% Unrecognized command found at '^' position.

==================================================== 

I really don't understand what's happening, since I read the c02642152.pdf manual and it's written there that it's possible to do it.

So, is it possible or not ?

If affirmative, could send me a step-by-step, plz?

Best regards,

[Peter_Debruyne]

Hi,

This is a basic IRF setup for 2 5120EI with the 2port 10G module in slot 1 of each switch.

Attached a simple diagram of the logical and physical IRF ports.

### IRF Config 5120
 # check current settings :
 # review default unit id and default priority (1)
 # firmware update : enabled
dis irf
dis int brief

#####################
# unit2 only:
sys
  # 1 is the current irf id
 irf member 1 renumber 2
 quit
dis irf configuration

quit
reset saved
reboot ( no save, irf unit id is saved in nvram, not in config file)

#####################
### unit 1 config
sys
 irf member 1 prio 32
  # verify
 dis irf
  # check current 10G interfaces and port numbers
dis int brief | i XG
 # current irf ports (disabled means no phy int !)
dis irf configuration

 int range ten 1/1/1 ten 1/1/2
  shut
  quit

 irf-port 1/1
  port group int ten 1/1/1
  port group int ten 1/1/2

 int range ten 1/1/1 ten 1/1/2
   undo shut

  save s f

#####################
# unit 2 - post reboot

dis int brief | i XG
sys
 int range ten 2/1/1 ten 2/1/2
  shut
  quit
 irf-port 2/2
   port group int ten 2/1/1
   port group int ten 2/1/2
 int range ten 2/1/1 ten 2/1/2
  undo shut
 save f

dis irf
dis irf configuration

### connect 10G cables
 # both units 1 and 2
irf-port-configuration active
 # unit 2 will be rebooting now and joining the IRF system
 
####################
# post irf config - wait for unit2 to have joined the IRF system

 # set member priority of unit2 (to avoid master problems when 2 would be master and new switch 3 would be joining)

irf member 2 priority 31

 # apply security to both console ports
 
local-user admin
 password simple hp
 service-type telnet ssh terminal
 auth level 3
 
user-int aux 0 1
 authentication-mode scheme

# save safely force (write mem)
s s f

### end


Best regards,Peter

IRF is limited to the 10 Gig expansion interfaces on that model. If you just have a stock box with no add on modules, it might well be true that you can't add any of the physical interfaces to the IRF logical port.

[Fredrik Lönnman]

You'll need the 10G expansion module.

[bgarcias]

So, there's no other way for me to configure IRF without the module?

[Fredrik Lönnman · Accepted solution]

No. Its pretty well described in the pdf you mentioned:

Connecting the IRF member switches
Prerequisites
To use the IRF feature, your switch must have at least one of the expansion interface modules in Table 1.
Only the ports on these modules can work as physical IRF ports.

Thanks a lot ! :-)

I linked two HP switches together via IRF (with A5500 JD374A as #1, and A5120 JD 375A as #2).

From console connection, I can see both switches linked and all the configuration formed as one. 

However, if I log into the switch via web (Web Management) -> Summary -> Device Information:

although I can see both members, I am UNABLE to click on member #2 and see its status. I am able to see the second member (click on it) via IRF -> To Configure Members..

I wonder if I missed anything?

Thanks!!!

OTOH, IRF between different models are not supported.. if it hasn't been added just lately.
