Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter6 Card and Service Configuration
Configuring Frame Relay Service
The possible errors for cnfln are:
• One or more parameters are invalid.
• Line does not exist (has not been added).
• Loopback or BERT is on.
• An active port already exists on this line.
Step 4 If the logical port does not exist or is not the appropriate type (Frame Relay, FUNI, or frame forwarding),
execute addport to create the appropriate type of port. If the logical port already exists and needs no
modification (cnfport), you can add connections by performing the tasks in “Adding a Frame Relay
Connection.” The parameters for addport depend on the type of FRSM.
For MGX-FRSM-2T3E3, or MGX-FRSM-HS2:
addport <port_num> <line_num> <port_type>
• port_num is the logical port number in the range 1–2. The mapping between a logical port and a line
is one-to-one for these cards. Note that the maximum committed information rate (CIR) on each line
for these cards is from 1 to 44210000 bps for MGX-FRSM-2T3, from 1 to 34010000 bps for
MGX-FRSM-2E3, and from 1 to 51840000 bps for MGX-FRSM-HS2. Specify CIR with addcon
(or addchan if necessary).
• line_num is the physical line number in the range 1–2.
• port_type is a number representing the mode of operation for the logical port: 1 for Frame Relay; 2
for FUNI mode-1a; or 3 for frame forwarding.
For an MGX-FRSM-2CT3:
addport <port_num> <line_num> <ds0_speed> <begin_slot> <num_slot>
<port_type>
• port_num is the logical port number in the range 1–256. When you subsequently add a connection
through the preferred command addcon or the addchan command (which requires NSAP format),
you must indicate a logical port by using this singular port_num regardless of the number of DS0s.
(You can add 1–24 DS0s to a single port_num through the other addport parameters.)
• line_num is the DS1 number in the range 1–56 to which you assign the DS0 when both lines are
active. If you activate only one line, the range is 1–28. You can assign up to 24 contiguous DS0s to
one DS1. Each physical line supports up to 28 DS1s. The number of DS0s cannot span more than
DS1.
• ds0_speed is a number representing the DS0 speed: 1 for 56 Kbps or 2 for 64 Kbps.
• begin_slot is the beginning DS0 timeslot in 1 base. For example, on port number 50, you could
specify begin_slot to be 9 then specify num_slot to be in the range 1–16.
• num_slot is the number of DS0s in the associated DS1. Note that the number of DS0s cannot be such
that the logical port spans more than DS1.
• port_type is a number representing the mode of operation for the logical port: 1 for Frame Relay; 2
for FUNI mode-1a; and 3 for frame forwarding.
