Hi All,
I have a 7206 router that has a PA-A3-3 card in it running IOS 12.2.46a
The router has the following config snippit in it:
interface ATM1/0.2 multipoint
description NEW Qwest DSL
no ip route-cache
no ip mroute-cache
pvc 5555555555 1/56
vbr-nrt 896 896 120
!
pvc 5555555556 1/98
vbr-nrt 1600 1600 120
!
etc.
It's been working fine for some time.
Anyway, as we know Cisco released the
Multiple Features Crafted UDP Vulnerability
so I tried loading IOS 12.2.33.SRD1 on it
to fix the vulnerability.
Everthing seemed to work except that the
new IOS bitched about the vbr-nrt statements.
If I changed the snippit above to:
interface ATM1/0.2 multipoint
description NEW Qwest DSL
no ip route-cache
no ip mroute-cache
pvc 5555555555 1/56
vbr-nrt 896 896 1
!
pvc 5555555556 1/98
vbr-nrt 1600 1600 1
!
etc.
it works. I tried running command line help and this is what i got:
router(config-if-atm-vc)#vbr-nrt ?
<1-44209> Peak Cell Rate(PCR) in Kbps
router(config-if-atm-vc)#vbr-nrt 320 ?
<1-320> Sustainable Cell Rate(SCR) in Kbps
router(config-if-atm-vc)#vbr-nrt 320 320 ?
<1-1> Maximum Burst Size(MBS) in Cells
<cr>
Why is the IOS suddenly not allowing MSB's larger than 1?
Ted
