N392 and N393
These parameters define the error threshold for the UNI formed by
the Express 5210
DTE
port and the attached frame relay device. If
the error threshold is met, the S
IGNAL
S
TATE
is changed to D
OWN
,
which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received. N392
defines the number of errors required in a given event window,
while N393 defines the number of polling events in each window.
For example:
If N392=3 and N393=4, then if three errors occur within any four
events the interface is determined

The status of the connection can be viewed in the S

Management DLCI (MGMT DLCI)
Enter the management data link connection identifier. The
M
ANAGEMENT
DLCI is a special DLCI used between the attached
DTE device and the Express 5210 to carry SNMP and TELNET
packets to/from the Express 5210 on the
DTE
port. See the
following section Guidelines for Configuring IP Addr, Subnet Mask,
and Mgmt DLCI for more information.

If the attached router or FRAD is used to route SNMP/TELNET
frames to the Express 5210, set the
M
ANAGEMENT
DLCI to a unique
value that identifies the virtual circuit between the router/FRAD
and the Express 5210. The router/FRAD must also be configured
to route the Express 5210

to 0.0.0.0 and setting the M

DLCI to a value not used by the attached frame relay device
disables this feature.
