SRT Bridging: Client Cannot Connect to Server
Possible Problem
Solution
Trying to bridge
frames containing
RIF from Token
Ring network to
Ethernet network
over an SRT
bridge
Use translational bridging instead of SRT bridging to allow
SRB-to-transparent bridging translation.
Because SRT bridging works only between Ethernet and Token
Ring, any packet containing a RIF is dropped when SRT bridging
is used.
Attempting to
transfer large
frame sizes
Problems will occur if Token Ring devices transmit frames
exceeding the Ethernet MTU
1
of 1500 bytes. Configure hosts on
the Token Ring to generate frame sizes less than or equal to the
Ethernet MTU.
Trying to bridge
protocols that
embed the MAC
address in the
Information field
of the MAC frame
(such as IP ARP,
Novell IPX, or
AARP)
If MAC addresses are embedded in the Information field of the
MAC frame, bridges will be incapable of reading the address.
Bridges will therefore be incapable of forwarding the traffic.
If you are attempting to bridge this type of protocol, route
the protocol instead.

If you still cannot communicate over the router, contact your
technical support representative.
2.
Media problem
Verify the line using the
show interfaces
exec command. If the
interface or line protocol is down, troubleshoot the media. For
LAN media, refer to the chapter that covers your media type.
