ELS Messages for TCP Header Compression
- Level:
- U-INFO
- Short Syntax:
- THC.001 init TCP hdr comp, tx slots txSlots
, rx slots rxSlots
, net net
- Long Syntax:
- THC.001 init TCP header compressor, tx slots txSlots
, rx slots rxSlots
, net net
- Description:
- The datalink has requested TCP header compressor to be initialized
on the specified net due to circuit coming up. The negotiated
transmit and receive slots are also specified.
- Level:
- U-INFO
- Short Syntax:
- THC.002 cleanup TCP hdr comp on net net
- Long Syntax:
- THC.002 cleanup TCP header compressor on net net
- Description:
- The datalink has requested TCP header compressor to be cleaned up
on the specified net due to either circuit coming up or going down.
- Level:
- UE-ERROR
- Short Syntax:
- THC.003 failed to proc pktType
, rsn ' reason
', net net
- Long Syntax:
- THC.003 failed to process ' pktType
', reason ' reason
', net net
- Description:
- TCP header decompressor has failed to process the specified packet
for the specified reason. Possible reasons could be any of
the following:
- the packet may be in error; either the length may be less
than 0 bytes for a full header, or may not have the
expected sequence number.
- the context may be in 'discard' state waiting for a full header
from the compressor or the context may have timed out.
- Level:
- U-INFO
- Short Syntax:
- THC.004 comp/decomp
ctx timed out, id contextId
, st ' contextState
', net net
- Long Syntax:
- THC.004 comp/decomp
ctx timed out, id contextId
, state ' contextState
', net net
- Description:
- A context in the specified state with the specified ID has timed out
at either the compressor or decompressor on the specified interface.
- Level:
- U-INFO
- Short Syntax:
- THC.005 send context_state timer, contexts in disc state contextsInDiscardState
, net net
- Long Syntax:
- THC.005 send context_state timer, contexts in disc state contextsInDiscardState
, net net
- Description:
- TCP header decompressor has the specified number of contexts in
discard state. The decompressor timer routine has timed out so
it can send out CONTEXT_STATE packets to the compressor so it
can send a FULL_HEADER packet to resynchronize the contexts between
the compressor and decompressor.
- Level:
- U-TRACE
- Short Syntax:
- THC.006 tx pktType
, src
: sp
-> dst
: dp
, len len
, id id
, net net
- Long Syntax:
- THC.006 transmit pktType
src
: sp
-> dst
: dp
, len len
, id id
, net net
- Description:
- A packet of the specified type is transmitted on the specified net
by either the TCP header compressor or the decompressor. The context
ID is also displayed.
- Level:
- U-TRACE
- Short Syntax:
- THC.007 rx pktType
, src
: sp
-> dst
: dp
, len len
, id id
, net net
- Long Syntax:
- THC.007 receive ' pktType
' src
: sp
-> dst
: dp
, len len
, id id
, net net
- Description:
- A packet of the specified type is received on the specified net
for the specified context ID. The length reflects the value
after decompression.
- Level:
- U-TRACE
- Short Syntax:
- THC.008 rx pktType
, len len
, net net
- Long Syntax:
- THC.008 receive pktType
, length len
, net net
- Description:
- A packet of the specified type and length is received on the
specified net.
- Level:
- CI-ERROR
- Short Syntax:
- THC.009 tx/rx
ContextState, len len
, id:seq [ contextId:lastValidSeq
], net net
- Long Syntax:
- THC.009 tx/rx
ContextState, len len
, id:seq [ contextId:lastValidSeq
], net net
- Description:
- A context_state packet has been either transmitted or received on
the specified interface for the specified list of context IDs with
the specified last valid sequence. This packet is transmitted either
because the context has timed out on the decompressor or the received
sequence number is not what the decompressor had expected to receive.
The compressor is expected to send a full header to the decompressor
to synchronize compression.
- Level:
- U-TRACE
- Short Syntax:
- THC.010 tx FullHeader src
: sp
-> dst
: dp
, len len
, id id
, rsn ' reason
', period period
, compPkts compPkts
, net net
- Long Syntax:
- THC.010 transmit FullHeader src
: sp
-> dst
: dp
, len len
, id id
, rsn ' reason
', period period
, compPkts compPkts
, net net
- Description:
- A full header packet is transmitted on the specified net by the
compressor for the specified reason. The reason could be any of
the following:
CtxChange - change in header context
MaxPeriod - max allowable comp packets between header refreshes
MaxTime - maximum time has passed between full headers
InvalidCtx - decompressor wishes a full header for this context
OutOfRangeDelta - delta value is out of range to be compressed
- Level:
- CI-ERROR
- Short Syntax:
- THC.011 fld to proc ' protocol
', rcvd seq( rxSeq
) != expected seq( expectedSeq
) for id CID
on net net
- Long Syntax:
- THC.011 failed to proc ' protocol
', rcvd seq( rxSeq
) != expected seq( expectedSeq
) for id CID
on net net
- Description:
- TCP header decompressor has failed to process the specified protocol
for the received sequence is not equal to the expected sequence for
the specified context ID on the specified net.
- Level:
- CI-ERROR
- Short Syntax:
- THC.012 pkt alloc fld for ctx state msg on net net
- Long Syntax:
- THC.012 failed to alloc pkt for context state msg on net net
- Description:
- TCP header decompressor failed to allocate a packet (I/O request
block) to transmit context state message on the specified net.
It tries to recover and transmit after some time.
- Level:
- CI-ERROR
- Short Syntax:
- THC.013 fld to alloc size
bytes mem for dataType
- Long Syntax:
- THC.013 failed to allocate size
bytes of memory for dataType
- Description:
- TCP header compression component has failed to allocate memory
of the specified size for the specified data type.
- Level:
- U-INFO
- Short Syntax:
- THC.014 fld to alloc new ctx id, active contexts activeContexts
, net net
- Long Syntax:
- THC.014 failed to alloc new context ID, active contexts activeContexts
, net net
- Description:
- TCP header compressor has failed to allocate a new context ID
for the number of active contexts has exceeded the max allowed.
