Hi,
The entries on the switches table does not seem write. The following is
a note I sent before to a user for vlan configuration. It has the same
concept except for vlan the snmp has to configured as "rw" while here it
just need to be "r". Hope this will help you.
#tabdump switches
#switch,snmpversion,username,password,privacy,auth,linkports,comments,disable
The username and password used in this table is NOT the ssh user name and
password. It's the SNMP user name and other info. One has to set it up on
the switch before calling xCAT vlan functions. You have to make sure
snmpwalk command works.
For SNMP v2, you just need to input the community name on the "passwword"
column. For SNMP v3, there are many things need to be setup. The
following is the help from snmpwalk command, from it you can tell what
needs to be configured on the switch for SNMP v3.
SNMP Version 1 or 2c specific
-c COMMUNITY set the community string
SNMP Version 3 specific
-a PROTOCOL set authentication protocol (MD5|SHA)
-A PASSPHRASE set authentication protocol pass phrase
-u USER-NAME set security name (e.g. bert)
-x PROTOCOL set privacy protocol (DES|AES)
-X PASSPHRASE set privacy protocol pass phrase
....
So to map the flags to the switches table:
For SNMP v2:
snmpversion --- 2c
password --- < -c COMMUNITY >
For SNMPv3
snmpversion --- 3
username --- <-u USER-NAME>
password --- <-A PASSPHRASE> <--- password will be used for both
-A and -X if -x is set.
privacy --- <-x PROTOCOL>
auth --- <-a PROTOCOL>
Here is an example:
xcatmn2:~ # tabdump switches
#switch,snmpversion,username,password,privacy,auth,linkports,commen,disable
"c160f1ql01","2c",,"c160snmp",,,,,
"switch1","3","admin","passw0rd","des","sha",,,,

here are the switch and switches tables entries:
Also i want to know the port entries in the switch table is correct format
or not?
