今天给这个问题作个小结 :
R2#show frame-relay lmi
LMI Statistics for interface Serial0/1 (Frame Relay DTE) LMI TYPE = CISCO
Invalid Unnumbered info 0 Invalid Prot Disc 0
Invalid dummy Call Ref 0 Invalid Msg Type 0
Invalid Status Message 0 Invalid Lock Shift 0
Invalid Information ID 0 Invalid Report IE Len 0
Invalid Report Request 0 Invalid Keep IE Len 0
Num Status Enq. Sent 0 Num Status msgs Rcvd 0
Num Update Status Rcvd 0 Num Status Timeouts 0
Last Full Status Req never Last Full Status Rcvd never
show frame lmi 只显示cisco的三种信令:cisco q933a ansi
R2(config-if)#frame-relay map ip 1.1.1.1 101 b
R2(config-if)#do show frame map
Serial0/1 (administratively down): ip 1.1.1.1
dlci 101(0x65,0x1850), static,
broadcast,
CISCO, status defined, inactive
R2(config-if)#encap frame ietf
R2(config-if)#do show frame map
Serial0/1 (administratively down): ip 1.1.1.1
dlci 101(0x65,0x1850), static,
broadcast,
IETF, status defined, inactive
注意,sh frame map 显示的是两种frame,即cisco和ietf
which command allows you to verify the encapsulation type (CISCO OR IETF) for a frame relay link?
根据题意要求,能看到CISCO或者IETF的,只有选A
