Local SRB: Host Cannot Connect to Server (continued)
Possible Problem
Solution
Ring number
mismatch
(continued)
•
conserve-ring
—(Optional) Keyword to enable SRB over
Frame Relay. When this option is configured, the SRB
software does not add the ring number associated with the
Frame Relay PVC,
3
the partner's virtual ring, to outbound
explorer frames. This option is permitted for Frame Relay
subinterfaces only.
Example:
In the following example, Token Rings 129 and 130 are
connected via a router:
interface tokenring 0
source-bridge 129 1 130
!
interface tokenring 1
source-bridge active 130 1 129
End system that
does not support
RIF

1.
Place a network analyzer on the same ring to which the end
system is connected.
2.
Look for RIF frames sent from the end system (RIF frames
have the high-order bit of the source MAC
5
address set to 1).
3.
If no RIF frames are found, the end system does not support
RIF and cannot participate in source routing.
If the protocol is routable, you can route the protocol or configure
transparent bridging. If you use transparent bridging, be careful
not to create loops between the SRB and the transparent bridging
domains.
4.
If your environment requires SRB, contact your workstation
or server vendor for SRB drivers or for information about
setting up your workstation or server to support SRB.
Hop count
exceeded
Use the
show
protocol
route
command to check the hop count
values on routers and bridges in the path. Packets that exceed the
hop count are dropped.
Alternatively, you can enable the
debug source event
privileged
exec command to see whether packets are being dropped because
the hop count has been exceeded.
