Introduction

show lane client Command
Briefly, the command reference describes the show lane client command as "To display detailed LANE information for all the LANE clients configured on an interface or any of its subinterfaces, on a specified subinterface, or on an emulated LAN."
This description, though correct, hides the importance of this command.
Output and Analysis
This section provides the show lane client command output and a line-by-line analysis.
Gambrinus#show lane client LE Client ATM2/0/0 ELAN name: default Admin:up State:operational Client ID: 2 LEC up for 15 minutes 39 seconds ELAN ID: 1 Join Attempt: 691 Last Fail Reason: Control Direct VC being released HW Address: 0060.4750.8402 Type: ethernet Max Frame Size: 1516 ATM Address: 47.009181000000006047508401.006047508402.00 VCD rxFrames txFrames Type ATM Address 0 0 0 configure 47.009181000000006047508401.006047508405.00 256 1 10 direct 47.009181000000006047508401.000000000002.01 257 476 0 distribute 47.009181000000006047508401.000000000002.01 258 0 56 send 47.009181000000006047508401.000000000003.01 259 2 0 forward 47.009181000000006047508401.000000000003.01 263 1 18 data 47.009181000000006047508401.006047508402.00 262 18 1 data 47.009181000000006047508401.006047508402.00 1. LE Client ATM2/0/0 ELAN name: default Admin: up State: operational
You can see that the client is up, operational. This is the correct state:
2. Client ID: 2 LEC up for 15 minutes 39 seconds
The only thing to keep in mind here is that the LAN Emulation Client (LEC) is up for only 15 minutes. Is this normal? Was there a maintenance 15 minutes ago?
3. Join Attempt: 691
Although high, this should not be a cause for concern. It does not necessarily indicate that the LEC went down 691 times. Perhaps the LECs were unreachable for a long period of time.
4. Last Fail Reason: Control Direct VC being released
This important field indicates that the last reason the LEC cannot reach the up, operational state was because it cannot reach the LAN Emulation Server (LES).
5. ATM Address: 47.009181000000006047508401.006047508402.0
This is only interesting when you check the show lane client command output of other LECs, which can be located at the remote side of a data direct.
6. 0 0 0 configure 47.009181000000006047508401.006047508405.00
This line gives detail on the connection to the LECs. This Virtual Channel Connection (VCC) is called the configure direct, as the Type field suggests. The VCC is 0, because the connection is torn down according to the specification.
7. 256 1 10 direct 47.009181000000006047508401.000000000002.01
This line gives detail on the connection to the LES. This VCC is called the control direct, as suggested by the Type field.
8. 257 476 0 distribute 47.009181000000006047508401.000000000002.01
This line gives detail on the connection from the LES to all LECs. It is called the control distribute. You can see that the LES address is identical for the control direct and control distribute, as it should be.
9. 258 0 56 send 47.009181000000006047508401.000000000003.01
This line gives detail on the connection to the Broadcast and Unknown Server (BUS). It is called multicast send, as the Type field suggests.
10. 259 2 0 forward 47.009181000000006047508401.000000000003.01
This line gives detail on the connection from the BUS to all LECs. It is called multicast forward. You can see that the BUS address is the same for the multicast send and multicast forward.
11. 263 1 18 data 47.009181000000006047508401.006047508402.00
The lines that remain give details on each data direct VCC. The ATM address corresponds to the remote LEC.
