cannot add new management ip address to same community string.

I would try the command without specifying a specific IP address and see how it responds.  Based on the information below.

Configuring Communities

Beginning in Privileged EXEC mode, use the following commands to

configure access rights for SNMPv1 and SNMPv2.

Command Purpose

configure Enter Global Configuration mode

snmp-server community

string [ro | rw | su]

[view view-name]

[ipaddress ip_address]

Configure the community string and specify access criteria

for the community.

• community-string — Acts as a password and is used to

authenticate the SNMP management station to the

switch. The string must also be defined on the NMS in

order for the NMS to access the SNMP agent on the

switch (Range: 1-20 characters)

• ro — Indicates read-only access

• rw — Indicates read-write access.

• view-name — Specifies the name of a previously defined

MIB view.

• ip_address — Specifies the IP address of the management

station. If no IP address is specified, all management

stations are permitted

I pulled this out of the User Guide page 325

Hope this helps,

Keep us updated if you can.

yes, if we dont specify anything it will allow all ips. this is what i dont want . i want specific ip to be addded.

it is allowing me to add one. but not the second one.

Thanks

MIK,

It looks like the options are

1.  Create another Community and specify the second Management Station IP.

2.  Use same Community and leave IP on command blank then create an ACL that only allows SNMP from those 2 hosts
