Thanks a million. Here is another enhancement for the COPS-PR dissector, it's relative to packet-cops.c,v 1.21 2002/02/22 21:52:09 This enchancement is able to use SNMP library (I used UCD) to print the textual names of the PIBs OIDs, if available. One of course needs to convert the PIB to MIB first (according to rules given in RFC 3159). I included a somewhat working version of DiffServ-PIB converted to MIB, for testing purposes. I also cleaned my earlier code a bit. Best Regards, Kari

DESCRIPTION
"The number of octets of IP Data, including IP Headers, that a stream may send without concern for policing."
SYNTAX INTEGER (0..'7FFFFFFF'h)
SnmpAdminString ::= TEXTUAL-CONVENTION
DISPLAY-HINT "255a"
STATUS current
DESCRIPTION "An octet string containing administrative information, preferably in human-readable form. To facilitate
internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using
the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard
from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that
do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes
should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading
or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an
alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8
encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus
the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the
number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that
is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for
any object instance does not exceed the limit of 128, as defined by [RFC1905]. Note that the size of an SnmpAdminString object is
measured in octets, not characters."
SYNTAX OCTET STRING (SIZE (0..255))
Prid ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Represents a pointer to a PRI, i.e,. to an instance of a PRC. The value is the OID name of the PRC's row definition, appended with
one sub-identifier containing the value of the InstanceId value for the referenced instance. The definition of an attribute with
this syntax can permit the attribute to have a value of 0.0 to indicate that it is not currently pointing to a PRI."

DESCRIPTION
"Represents a tag value, such that all instances of a particular PRC having the same tag value form a tag list. A tag list is
identified by the tag value shared by all instances in that tag list."
SYNTAX Unsigned32 (1..4294967295)
TagReferenceId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Represents a reference to a tag list of instances of a particular PRC. The particular PRC must have an attribute with the syntax of
TagId. The tag list consists of all instances which have the same value of the TagId attribute. Reference to the tag list is via the
attribute with the syntax of TagReferenceId containing the tag value which identifies the tag list. The definition of an attribute
with this syntax can permit the attribute to have a value of 0 to indicate that it is not currently referencing a tag list."

in a PIB-INDEX clause. The value of an attribute with this syntax is always greater than zero. PRIs of the same PRC need not have
contiguous values for their instance-identifying attribute."
SYNTAX Unsigned32 (1..4294967295)
PrcIdentifier ::= TEXTUAL-CONVENTION

DESCRIPTION
"An OID that identifies a PRC. The value MUST be an OID assigned to a PRC's row definition. An attribute with this syntax can have
the value 0.0 (zeroDotZero) to indicate that it currently does not identify a PRC."

interface, while 'outbound' traffic is operated on prior to transmission on the interface."
SYNTAX INTEGER {
inbound(1), -- ingress interface
outbound(2) -- egress interface
}
AttrIdentifier ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A Unsigned32 value that identifies an attribute in a PRC. A AttrIdentifier value is always interpreted within the context of a
PrcIdentifier value. The PrcIdentifier object which defines the context must be registered immediately before the object which uses
the AttrIdentifier textual convention. An attribute with this syntax can have the value 0 to indicate that it currently does not

represents the depth of the queue, pointed to by qosAlgDropQMeasure, at which all newly arriving packets will be dropped. The
headDrop(3) algorithm is described as follows: if a packet arrives when the current depth of the queue, pointed to by
qosAlgDropQMeasure, is at qosAlgDropQThreshold, packets currently at the head of the queue are dropped to make room for the new
packet to be enqueued at the tail of the queue. The randomDrop(4) algorithm is described as follows: on packet arrival, an
algorithm is executed which may randomly drop the packet, or drop other packet(s) from the queue in its place. The specifics of
the algorithm may be proprietary. For this algorithm, qosAlgDropSpecific points to a qosRandomDropEntry that describes the
algorithm. For this algorithm, qosAlgQThreshold is understood to be the absolute maximum size of the queue and additional
parameters are described in qosRandomDropTable. The alwaysDrop(5) algorithm always drops packets. In this case, the other
configuration values in this Entry are not meaningful; The queue is not used, therefore, qosAlgDropNext, qosAlgDropQMeasure, and
qosAlgDropSpecific should be all set to zeroDotZero. The mQDrop(6) algorithm measures multiple queues for the drop algorithm. The
