DLCI Type
Possible Settings: Standard, Multiplexed, IP Enabled
Default Setting:
For user data port DLCIs:
Standard
For network interface DLCIs:
Multiplexed
Specifies whether the DLCI is standard or multiplexed. This field is read-only when the
selected DLCI is used in a PVC or Management link connection and the DLCI Type is
Standard.
Display Conditions
– This option does not appear for a user data port or a virtual router
port, and it cannot be changed if the DLCI is specified as the TS Access Management
Link.
Standard – Supports standard DLCIs as specified by the Frame Relay Standards. Use
this setting when a non-FrameSaver unit is at the other end.
Multiplexed – Enables multiplexing of multiple connections into a single DLCI. Allows a
single PVC through the frame relay network to carry multiple DLCIs as long as these
connections are between the same two endpoints (proprietary). Do not select Multiplexed
unless there are FrameSaver units at both ends of the connection.
IP Enabled – Enables connection to one or more endpoints through a Layer 3 network. A
Payload Management PVC is created as well as the IP Enabled DLCI.
CIR (bps)
Possible Settings: 0 – 1536000
Default Setting: 0
Determines the data rate for the DLCI that the network commits to accept and carry
without discarding frames; the CIR in bits per second. Entry of an invalid rate causes the
error message
Value Out of Range (0 –
x
)
, where
x
= the maximum line rate
available on the port.
0 – 1536000 – Specifies the network-committed data rate.
Tc
Possible Settings: 1 – 65535
Default Setting: Read Only
Displays the DLCI’s calculated value of its committed rate measurement interval (Tc) in
milliseconds. This value is calculated based upon the settings for the Committed Burst
Size Bc (Bits) and CIR (bps) options.
Committed Burst Size Bc (Bits)
Possible Settings: CIR, Other
Default Setting: CIR
Specifies whether the DLCI’s committed burst size will follow the CIR, or whether it will be
entered independently. This value is the maximum amount of data that the service
provider has agreed to accept during the committed rate measurement interval (Tc).
CIR – Uses the value in the CIR (bps) option as the committed burst size (Bc). The Bc and
excess burst size (Be) options are updated when a CIR update is received from the
network switch.
Other – Allows you to specify the committed burst size for the DLCI. When Other is
selected, the Bc and Be values must be manually entered and maintained, as well.
