We have a new Cisco SG500X-24 as a candidate for replacing a Dell 5324. Our C++ application programs the switch VLAN membership for dot1qVlanForbiddenEgressPorts, dot1qVlanStaticUntaggedPorts, and others. I have found that the Cisco switch requires a different format for the membership bit mask in the SNMPSET command. For example, the existing switch obeys the command
snmpset -v2c -c <community> <ip:port> 1.3.6.1.2.1.17.7.1.4.3.1.3.<vlan> x "DD D7 F0"
but the Cisco switch requires
snmpset -v2c -c <community> <ip:port> 1.3.6.1.2.1.17.7.1.4.3.1.3.<vlan> x "00 00 00 00 00 00 DD D7 F0 00"
Notice the leading 6 bytes in the bit mask string. Is this an issue of Cisco using a proprietary implementation, conforming to a more recent RFC, or is it possible I can change a mode setting on the switch to make the SNMP command obey the one shown first?

Hello,
the SG500 series is kind of a stripped down version of the higher end switches (which cost a lot more obviously). I wonder if you get the same with a 'real' Cisco higher end Catalyst switch. Do you have the possibility to test on one ?

No, I've got only this single switch to work with.
