Chapter 7 149
The output from the atmmgr
card_inst_num
show -v command shows
all currently active VCs for the specified adapter. The above example
shows this information:
• The VC used by the signaling protocol (0,5). The destination IP
address is displayed as N/A (not applicable).
• The VC used by ILMI (0,16). The destination IP address is displayed
as N/A (not applicable).
• One PVC used by Classical IP, where the destination IP address is
not yet resolved. This could occur when the PVC is not yet completely
configured on both systems and all intermediate switches.
• The VCs used by the two LECs. Each LEC is identified by its unique
Selector (“SEL”) value and belongs to a specific ELAN. Note that the
ELAN whose Selector is 02 is a Token Ring ELAN (as denoted by
8025 in the “Use” field for the ELAN connections). The ELAN whose
Selector is 56 is an Ethernet ELAN.
For the VCs used by the two LECs, all connections from the LEC to
the LECS, LES, and destination LEC are shown. The ELAN
connections for an ELAN interface are the following:
— LEC_to_LECS/LES: Two SVCs are displayed—one for the
bidirectional point-to-point Configuration Direct VCC set up
between the LEC and the LES, and another for the bidirectional
point-to-point Control Direct VCC setup between the LEC and
the LES.
— LEC_to_BUS: Two SVCs are displayed for the VCCs set up
between the LEC and the BUS—one for the bidirectional
Multicast Send VCC set up, and the other for the Multicast
Forward VCC.
— LEC_to_LEC: One SVC is displayed for the Data Direct VCC set
up between the two LECs that want to exchange data.
For more information about LAN Emulation, see “Summary of
LAN Emulation” on page 40.
Note that the destination IP address is applicable only for the
LEC-to-LEC VC. However, for the LEC-to-LEC VC you must
manually obtain the destination IP address using the elarp and
arp commands. See “Getting a LEC-to-LEC SVC’s Destination
IP Address” on page 150. For more details about the elarp and
arp commands, see the elarp and arp man pages.
