Known Software Limitations Part No. T0001-42, Rev C October, 2002 Page 55 of 103 Password Limitation BGP - All Products The Vanguard Router supports limited passwords. Cisco supports MD5. Currently we do not have Authentication compatible with Cisco. MD5 should be supported in the Vanguard products in future releases. (DRFaa18829) Workaround: At present, there is no workaround. Vanguard 6560 Redial Timer On a Vanguard 6560 if the redial time in the switched service is changed (from its default of 300 seconds) to a value that is less then it takes frame relay to establish its control protocol, then switched services places another call before the first one completes. This creates a call collision and both calls are cleared. (DRFaa18849) Workaround: Increase the redial time in the switched services record so that it is greater than the time required for the frame relay port to declare itself up. Any value greater than 60 seconds should be sufficient. IP Fragmenting - Vanguard 6560 Fragmenting occurs when a Vanguard 340 and Vanguard 6560 are running software using tunneling between two sites for Intranet traffic. (Both devices are configured for standard IP routing over FR bypass, with MTU=1500 on all IP interfaces.) When IP packets greater than 1500 bytes try to pass through the tunnel, the tunnel does not fragment the packets, it forwards them as they are. (DRFaa18942) Workaround: Reduce MTU to a number less than 1500 bytes. Vanguard 6450 Limitation The Vanguard 6450 is limited to a maximum of 64 LLC-SDLC Stations when the Local Port Pool Heap has been configured to a non-zero value. (DRFaa19027) Workaround: Because the Vanguard 6450 has a maximum installed memory of 16 Megabytes, it is recommended to use the Vanguard 6455 with 32 Megabytes installed if the number of supported LLC-SDLC Stations exceed 64. Building Older Images Follow the instructions listed in the workaround to revert back to an older build image (if you have installed the Vanguide Application Release 6.0.R00A from the 6.0.R00A CD). (DRFaa18867) Workaround: Start Vanguide Software Builder, insert the older Vanguide release CD (A release before 6.0.R00A, example: 5.6.R000 CD) into CD driver. In Vanguide Software Builder, select the "Settings" menu, then change "CD ROM directory:" to say D:\Motorola (if D is the CD driver letter). Then you are able to build an image for a release before 6.0.R00A.

Known Software Limitations
Page 55 of 103
Password Limitation BGP - All Products
The Vanguard Router supports limited passwords. Cisco supports MD5. Currently
we do not have Authentication compatible with Cisco. MD5 should be supported in
the Vanguard products in future releases. (DRFaa18829)
Workaround:
At present, there is no workaround.
Vanguard 6560 Redial Timer
On a Vanguard 6560 if the redial time in the switched service is changed (from its
default of 300 seconds) to a value that is less then it takes frame relay to establish its
control protocol, then switched services places another call before the first one
completes. This creates a call collision and both calls are cleared. (DRFaa18849)
Workaround:
Increase the redial time in the switched services record so that it is
greater than the time required for the frame relay port to declare itself up. Any value
greater than 60 seconds should be sufficient.
IP Fragmenting - Vanguard 6560
Fragmenting occurs when a Vanguard 340 and Vanguard 6560 are running software
using tunneling between two sites for Intranet traffic. (Both devices are configured
for standard IP routing over FR bypass, with MTU=1500 on all IP interfaces.) When
IP packets greater than 1500 bytes try to pass through the tunnel, the tunnel does not
fragment the packets, it forwards them as they are. (DRFaa18942)
Workaround:
Reduce MTU to a number less than 1500 bytes.
Vanguard 6450 Limitation
The Vanguard 6450 is limited to a maximum of 64 LLC-SDLC Stations when the
Local Port Pool Heap has been configured to a non-zero value. (DRFaa19027)
Workaround:
Because the Vanguard 6450 has a maximum installed memory of 16
Megabytes, it is recommended to use the Vanguard 6455 with 32 Megabytes
installed if the number of supported LLC-SDLC Stations exceed 64.
Building Older Images
Follow the instructions listed in the workaround to revert back to an older build
image (if you have installed the Vanguide Application Release 6.0.R00A from the
6.0.R00A CD). (DRFaa18867)
Workaround:
Start Vanguide Software Builder, insert the older Vanguide release CD
(A release before 6.0.R00A, example: 5.6.R000 CD) into CD driver. In Vanguide
Software Builder, select the "Settings" menu, then change "CD ROM directory:" to
say D:\Motorola (if D is the CD driver letter). Then you are able to build an image
for a release before 6.0.R00A.
