Vanguard 7300 Series ATM CBR Station Configuration
Occasionally Constant Bit Rate ATM stations were deactivated. (The total aggregate
PCR did not exceed the link speed.) This occurs because the CBR scheduling is very
rigid and has to fit into the transmit scheduling table in a certain way. Even though it
appears that bandwidth is available, if it does not fit in the scheduling table, the
station is not created. To increase the chances of fitting into the scheduling table, the
larger CBR entries (PCR rate) should be created first. (DRFaa18518)
Workaround:
Use VBR stations instead.
Vanguard 7300 Series Embedded Web Group Configuration
When you configure the voice port interface type (FXS), the next parameter is
Signaling Mode. When you change the port interface type to E&M, the next
parameter should change to Signal Type. Currently the next menu displayed is
Signaling Mode. (DRFaa18769)
Workaround: At present, there is no workaround.
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.
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.R000 from the
6.0.R000 CD). (DRFaa18867)
Workaround: Start Vanguide Software Builder, insert the older Vanguide release CD
(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.R000.
Vanguard 7300 Port Speed
The "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen is
the configured Port Speed for the Vanguard 7300 Serial Port. If the "Clock Source"
parameter in the FRI, PPP, X25, SDLC, or TBOP serial port is set to EXT or EXTLP,
the "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen may
not match the speed of the actual clock on the serial line. (DRCaa21740)
Workaround: To determine the actual speed on the serial line, an external datascope
or protocol analyzer needs to be attached. The "Clock Speed" parameter in the Port
Record needs to be configured to the actual Clock Speed that the port is attached to.
Improper Default Bridge Link/Router Interface Numbers for LAN Ports
Vanguard 7300 Series
All LAN ports receive the same default bridge link (1) and router interface number
(1) when the node is defaulted. (DRCaa21838)
Workaround: Configure each LAN port with a unique bridge link and router
interface number, then warm-boot the node.
