ELS Messages for IP Tunnel Subsystem
- Level:
- UI-ERROR
- Short Syntax:
- IPT.001 Inv dst name
- Long Syntax:
- IPT.001 Invalid destination name
- Description:
- The destination configured for the tunnel is invalid.
The name is either unknown or it is not a valid IP address.
- Level:
- UE-ERROR
- Short Syntax:
- IPT.002 Drop inv pkt from address
, prot protocol
- Long Syntax:
- IPT.002 Dropping invalid packet from address
, protocol protocol
- Description:
- A tunnel packet was dropped because it either had an invalid
source address (which did not correspond to any tunnel's
destination address) or because the data payload within
the packet was not configured within the destination tunnel.
- Level:
- C-INFO
- Short Syntax:
- IPT.003 Rcv protocol
pkt from name
( address
)
- Long Syntax:
- IPT.003 Receiving protocol
packet from name
( address
)
- Description:
- A tunneled packet was received from the specified tunnel endpoint.
- Level:
- C-INFO
- Short Syntax:
- IPT.004 Snd protocol
pkt to name
( address
)
- Long Syntax:
- IPT.004 Sending protocol
packet to name
( address
)
- Description:
- A tunneled packet was transmitted to the specified tunnel endpoint.
- Level:
- UI-ERROR
- Short Syntax:
- IPT.005 Too many encaps, drop pkt
- Long Syntax:
- IPT.005 Too many encapsulations, dropping packet
- Description:
- The tunnel header can not be prepended to the packet due to
insufficient header space.
- Cause:
- The packet is passing through multiple tunnels.
- Action:
- Reconfigure to guarantee packets only pass through one tunnel.
- Level:
- UE-ERROR
- Short Syntax:
- IPT.006 Endpt name
( address
) unrch, deny conn req
- Long Syntax:
- IPT.006 Endpoint name
( address
) unreachable, denying connection request
- Description:
- The local router transmitted a UDP Discard packet to the named
remote tunnel endpoint to determine if the tunnel can be created.
The UDP packet was returned as undeliverable thus connections to
this remote destination by upper layers in the stack must be denied.
- Cause:
- The destination address is incorrect or the remote tunnel
endpoint is down.
- Level:
- UE-ERROR
- Short Syntax:
- IPT.007 Prot protocol
unavail at dest name
( address
)
- Long Syntax:
- IPT.007 Protocol protocol
unavailable at destination name
( address
)
- Description:
- The named remote endpoint is not accepting packets of the specified
type. If the tunnel is not encrypted or authenticated then
the IP Tunnel is disconnected. Otherwise, the tunnel is
left up but packets are discarded rather than risk the
transmission of that data via unsecured interfaces.
- Cause:
- The remote tunnel endpoint is misconfigured or it does not
support the protocol which this tunnel is attempting to use.
- Level:
- UE-ERROR
- Short Syntax:
- IPT.008 Endpt name
( address
) unrch, disc tnl
- Long Syntax:
- IPT.008 Endpoint name
( address
) unreachable, disconnect tunnel
- Description:
- The remote tunnel endpoint has become unreachable. It is
either down or the path to it is down due to the failure of
an intermediate router.
- Level:
- C-INFO
- Short Syntax:
- IPT.009 Rstrt MTU disc, MTU= MTU
, dest name
( address
)
- Long Syntax:
- IPT.009 Restarting MTU discovery, MTU= MTU
, destination name
( address
)
- Description:
- The MTU discovery interval has elapsed so the MTU (maximum
packet size) for the specified destination has been reset to
its configured initial value.
- Level:
- C-INFO
- Short Syntax:
- IPT.010 Rcv'd Frag Req'd. Adjusting MTU old MTU
to new MTU
, dest name
( address
)
- Long Syntax:
- IPT.010 Received Fragmentation Required. Adjusting MTU from old MTU
to new MTU
, destination name
( address
)
- Description:
- Some router along the path from the local router to the specified
destination rejected a packet because it was too large. MTU
discovery is enabled so the MTU is automatically adjusted downward
so subsequent packets can be transmitted without fragmentation.
This event may occur several times until an MTU is found which
does not require fragmentation within the tunnel.
- Level:
- UI-ERROR
- Short Syntax:
- IPT.011 Rcv'd Frag Req'd but MTU discovery disabled, dest name
( address
)
- Long Syntax:
- IPT.011 Received Fragmentation Required but MTU discovery is disabled, destination name
( address
)
- Description:
- Some router along the path between the local router and the specified
destination rejected a packet because it was too large. The local
router can not adjust its packet size because MTU discovery has
been disabled by the user.
- Action:
- Enable MTU discovery.
- Level:
- UI-ERROR
- Short Syntax:
- IPT.012 All tnl slots full, refuse con req to dest name
( address
)
- Long Syntax:
- IPT.012 All tunnel slots are full, refusing connection req to destination name
( address
)
- Description:
- The number of simutaneously connected remote endpoints has
reached its configured limit. Additional connection requests
must be refused.
- Action:
- Increase the number of simultaneous endpoints via the Tunnel
configuration commands.
- Level:
- UE-ERROR
- Short Syntax:
- IPT.013 MTU driven to ZERO, dest name
( address
)
- Long Syntax:
- IPT.013 Maximum Transfer Unit has been reduced to ZERO, destination name
( address
)
- Description:
- MTU discovery has lowered the MTU all the way down to ZERO.
This is an error condition which only occurs if a tunnels
are misconfigured such that a TUNNEL's interface address
is used as the tunnel DESTINATION address in another router.
The tunnel interface on the local router is marked down.
- Action:
- Verify the IP tunnel destination address refers to an address
on a PHYSICAL interface on the remote router. This can be a
dial-up circuit or a physical leased line. It can NOT address
another IP tunnel's IP address.
- Level:
- UI-ERROR
- Short Syntax:
- IPT.014 Rcv'd Frag Req'd. Pkt dscrd, dest name
( address
)
- Long Syntax:
- IPT.014 Received Fragmentation Required. Packet discarded, destination name
( address
)
- Description:
- Some router along the path between the local router and the specified
destination rejected a packet because it was too large. The tunnel on
the local as gone down and come up again since the original packet
was sent out. This message indicates there is a problem bringing
the tunnel up which may be remedied by enabling MTU discovery to
the specified destination.
- Action:
- Enable MTU discovery.
