CER - Creating VLANs via SNMP - cant set name?

Post #1 of 3 (1236 views)

Hi everyone,

Im writing some scripts that create VLANs and assigns ports to them via
SNMP, and so far everything is working pretty good, except that when I
create the VLAN, it doesnt seem to save the name that I supply along with
it. For example, when I execute the following command:

snmpset -v2c -c.... x.x.x.x .1.3.6.1.2.1.17.7.1.4.3.1.1.123 s TEST
.1.3.6.1.2.1.17.7.1.4.3.1.2.123 x 0x00 .1.3.6.1.2.1.17.7.1.4.3.1.4.123 x
0x00 .1.3.6.1.2.1.17.7.1.4.3.1.5.123 i 4

VLAN 123 is created, but the name TEST is not applied:

#sh vlan brief

Configured PORT-VLAN entries: 5
Maximum PORT-VLAN entries: 4095
Default PORT-VLAN id: 1

VLAN Name Encap ESI Ve Pri Ports

---- ---- ----- --- ----- --- -----

1 DEFAULT-VL - - Untagged
Ports : e 1/1 to 1/24 e 2/1 to 2/4
123 [None] - - Statically
tagged Ports : e 1/10 to 1/11

FWIW the above command works fine on other switches that I am testing
against, they all save the name as expected.

Attempting to set the name afterwards via a separate snmpset doesnt yeild
any better results.

Does anyone know what Im doing wrong here? Should I be poking a different
OID perhaps?

Running:

System: NetIron CER (Serial #: ...., Part #: ....)
Boot : Version 5.6.0cT185 Copyright (c) 1996-2013 Brocade
Communications Systems, Inc.
Monitor : Version 5.6.0cT185 Copyright (c) 1996-2013 Brocade
Communications Systems, Inc.
IronWare : Version 5.6.0dT183 Copyright (c) 1996-2013 Brocade
Communications Systems, Inc.

Software might be a bit old, could probably try a new version if people
think that might help.

Cheers
Tom

Hi,

1.3.6.1.2.1.17.7.1.4.3 is read-only. Have a look at
1.3.6.1.4.1.1991.1.1.3.2.7.1.21 instead.

snmpwalk -v2c -c $COMMUNITY $IP 1.3.6.1.4.1.1991.1.1.3.2.7.1.21
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.123 = STRING: "TEST2"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.124 = STRING: "VLAN124"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.125 = STRING: "VLAN125"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.126 = STRING: "VLAN126"

snmpset -v2c -c $COMMUNITY $IP iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.123 s
HELLOMYFRIEND
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.123 = STRING: "HELLOMYFRIEND"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.124 = STRING: "VLAN124"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.125 = STRING: "VLAN125"
iso.3.6.1.4.1.1991.1.1.3.2.7.1.21.126 = STRING: "VLAN126"

You can also take a look at some other tools than can configure advanced
things via ssh or telnet or can inject whole configurations.

Some people use

Netmikto
https://github.com/ktbyers/netmiko

and there is also kind of official brocade client called clicrud
https://github.com/DavidJohnGee/clicrud

I did my own injection client a while ago to escape the python world.

Hi Jörg,

Much appreciated! I am back in business with this OID. I still cant seem to
create and set the VLAN name in one operation, but with this OID I can
create and then set its name afterwards in a two step operation which is
fine.

Maybe I can if I play around using only OIDs from this MIB some more...
