a3ComSysSystemProtocolMask

Module: A3COM-SWITCHING-SYSTEMS-MIB

OID (symbolic): A3COM-SWITCHING-SYSTEMS-MIB::a3ComSysSystemProtocolMask

OID (numeric): 1.3.6.1.4.1.43.29.4.1.17

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This object is a bit mask that indicates which protocols exist in the software image currently loaded in memory. The value of this OBJECT is a sum. It initially takes on the value 0, then for each protocol bit as defined below, 2 raised to the value of the (bit position - 1) is added to the sum.

The following bits are defined:

IP_ROUTING 0x00000001 IPX_ROUTING 0x00000002 DDP_ROUTING 0x00000004

A value of 0x00000000 indicates the standard switching software.

What is a3ComSysSystemProtocolMask?

This integer bitmask shows which routing protocols are compiled into the currently loaded software image. Engineers use this to verify protocol support and understand the device's switching capabilities across IP, IPX, and DDP. A value of 0x00000001 indicates only IP routing is enabled, while 0x00000007 means all three protocols are available.

Examples
