Re: OID for MIBs

Hi Alan,

Thank you for the clarification.

I am working in enterprise-1 and hence defined private mib for their
products with iso.3.6.1.4.1.PEN1.1
and now the enterprise-1 has been acquired by enterprise-2.

Is it okay to retain mib-oid for already existing products and change only
SNMPv2-MIB::sysDescr
i.e private mib  oid of enterprise-1 already existing product-1
=.1.3.6.1.4.1.PEN1.1
However its SNMPv2-MIB::sysDescr = Enterprise-2 name


Thank you,
Pushpa.T
