dsmonHostCtlIPv6PrefixLen

Module: DSMON-MIB

OID (symbolic): DSMON-MIB::dsmonHostCtlIPv6PrefixLen

OID (numeric): 1.3.6.1.2.1.16.26.1.4.1.1.6

Node type: OBJECT-TYPE

Type: Integer32

Access: read-create

Description: The number of 'leftmost' contiguous bits in the host address field for encapsulations of IPv6, that should be maintained in this collection. This object controls how the dsmonHostAddress object is derived for packets which contain an encapsulation of IPv6.

If this object has a value less than 128, then 'm' rightmost bits, where 'm' is equal to '128 -

dsmonHostCtlIPv6PrefixLen', will be cleared to zero for counting purposes only. The 'leftmost' bit is the most significant bit of the first network-byte-order octet of the address.

If this object is equal to 128, then no bits are cleared in each dsmonHostAddress field.

This object MUST NOT be modified if the associated dsmonHostCtlStatus object is equal to active(1).

What is dsmonHostCtlIPv6PrefixLen?

Sets how many leading bits of an IPv6 host address are kept (the rest zeroed) when building dsmonHostAddress entries, the IPv6 counterpart of dsmonHostCtlIPv4PrefixLen, defaulting to the full /128.
