DSPU can generate LLC, SDLC or QLLC to test STUN,
FRAS/FRAS Host, RSRB OR DLSW.
Basically, you configure:
RA = downstream PU (command is "dspu host")
RB = Host (command is "dspu pu")
yes, I know.. it looks backwards cuz they are pointing
to each other.
Anyways, you need 4 routers. RA & RB is the pu/host
and not necessary to run DLSW while R1 & R2 is say
your DLSW Routers...so
RA---R1--R2--RB
RA global config would be:
dspu host RB_ethernet xid-send 22222222 rmac
2222.2222.2222 rsap 2 lsap 2
dspu host RB_tokenring xid-send 88888888 rmac
8888.8888.8888 rsap 8 lsap 8
Note:
1. for host name...I created any name
2. for xid-send ...I created any number
3. for remote mac (rmac) I created any mac but choose
specifically all 2 or 8 or any number cuz it is easier
to remember if I need to bit swap. See:
http://www.cisco.com/cgi-bin/Support/Bitswap/bitswap.pl
4. same thing for rsap/lsap..any number
so all this for consistency and ease of memorization.
Anyways, back to the config:
int to0
mac-address 3333.3333.3333
ip add x.x.x.x/24
dspu enable-host lsap 8
dspu start RB_tokenring
int e0
mac-address 5555.5555.5555
ip add x.x.x.x/24
dspu enable-host lsap 2
dspu start RA_ethernet
Again, I arbitrarily choose whatever mac address and
then enable the dspu to link it to the global config,
then started the dspu traffic.
RB global:
dspu pu RA_token rmac 3333.3333.3333 rsap 8 lsap 8
dspu pu RB_ethernet rmac aaaa.aaaa.aaaa rsap 2 lsap 2
int to0
mac-address 8888.8888.8888
ip add x.x.x.x/24
dspu enable-pu lsap 8
dspu start RA_token
int e0
blah blah
I am doing this from memory so i hope the configs
work, but I think you get the idea.
