Hey guys,
Looking to do the IE and was wondering how many of you guys have
used GNS3 and how is it? Would it be adequate tool to prepare for the lab?
Any feedback is appreciated.
Thx..

Subject: Re: [OSL | CCIE_RS] snmp engine id
Hi Taqdir,
The engine id is used with the snmp user password to generate the MD5 digests
(the system will not store the passwords - just the engine id and MD5, so if
one or the other changes, you need to use the password and regenerate the MD5
hash. RFC2274 discusses the user security model)
Another thing I think was introduced with SNMPv3 but I'm pretty sure can also
be used with SNMP 2c is the use of SNMP Views. This basically allow limiting
which parts of the MIB tree that can be looked at for a particular user or
community, an example would to allow a managed customer to pull out interface
stats and cpu load but not see everything else...
Cheers,
Adam

Hi All,
In snmp v1 and v2c there was no concept of engine id and no authentication and
encryption
so snmp v3 came with md5 authentication and encryption of packets.
what is the purpose of snmp engine id local and remote in snmp v3? ....
default is also set...
