The IP Over NBMA (ION) Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] comments on draft-ietf-iplpdn-frmib-dte-07.txt
Carolyn, Fred, and Charles,
I am sorry that these comments are so late. I just found out about this
new iteration of RFC1315 at the last Frame Relay Forum meeting from Andy
Malis. At the same time our offices was moving and I just was able to retrieve
a copy of the proposed MIB for the Montreal IETF June 24, 1996.
How do I get on the proper distribution list for these discussions. Andy
gave me ion and it did not seem right. Please forward this mail to the
proper distribution list.
Comments:
1. We believe that a definition of frTrapState at the interface
basis is more useful for some vendors than for all interfaces.
Some interfaces may be managed by different agents than others.
I would suggest that frDlcmiTrapState be added to the frDlcmiTable.
2. The frDlcmiTable does not support bidirectional signalling. Will
this be a problem for the future? Currently, I know of no DTE
vendor that supports bidirectional signalling.
3. frClcmiAddressLen is not adequate. Since the MIB is going to be
changed, I suggest the same definition as frLportAddrDLCILen from
RFC 1604 be used.
4. The MIB does not support different quality of service parameter
(CIR, Bc, Be) on a per direction basis. Is this a problem for the
future.
5. The following statistics would be helpful in the frDlcmiTable:
frDlcmiLinkRelErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of user-side local in-channel
signaling link reliability errors (i.e., non-
receipt of Status/Status Enquiry messages or
invalid sequence numbers in a Link Integrity
Verification Information Element) for this UNI/NNI
logical port. If the logical port is not
performing user-side procedures, then this value
is equal to noSuchName."
REFERENCE "ITU Q.933 Annex A and ANSI T1.617 Annex D"
::= { frDlcmiEntry 13 }
frDlcmiProtErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of user-side local in-channel
signaling protocol errors (i.e., protocol
discriminator, message type, call reference, and
mandatory information element errors) for this
UNI/NNI logical port. If the logical port is not
performing user-side procedures, then this value
is equal to noSuchName."
REFERENCE "ITU Q.933 Annex A and ANSI T1.617 Annex D"
::= {frDlcmiEntry 14 }
frDlcmiChanInactive OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of times the user-side channel was
declared inactive (i.e., N392 errors in N393
events) for this UNI/NNI logical port. If the
logical port is not performing user-side
procedures, then this value is equal to
noSuchName."
REFERENCE "ITU Q.933 Annex A and ANSI T1.617 Annex D"
::= { frDlcmiEntry 15 }
6. What is the interrelationship between frCircuitMulticast and
frDlcmiMulticast? Can frCircuitMulticast be set to anything
other than unicast if frDlcmiMulticast is nonBroadcast? Can the
same interface have both unicast and multicast DLCI? If so,
what is the setting of frDlcmiMulticst set?
7. What provisions are being made for SVCs or is it out of the
scope of this MIB modification?
8. The following statistics would be useful either as part of frDlcmiTable
or part of a separate table:
frErrorUserLinkRelErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION -- (from RFC1604 frMgtVCSigUserLinkRelErrors)
"The number of user-side local in-channel

performing user-side procedures, then this value
is equal to noSuchName."
