Known Software Limitations Page 30 of 55
Single DLCI Multiplexing SNA/IP/IPX Causes Node Crash - All Products
RFC1490 Single DLCI Multiplexing and De-Multiplexing SNA/IP/IPX will cause
the node to crash. If you configure the string FRISNA-xSy as either a source or
destination in the PVC Setup Table and then boot the node, the node will not come
up. The node will repeatedly crash. Multiplexing IP and IPX in the same DLCI
works fine. (DRFaa16306)
Workaround: At present, there is no workaround.
VPN Tunnels with RUIHC Limitation - All Products
Configuring the maximum number of Tunnels (255) with RUIHC on each tunnel.,
causes the node to not come up or reset continually. (DRFaa17913)
Workaround: To configure and use the maximum number of tunnels with RUIHC
(255) use tunnel boot instead of node boot. In the RUIHC profile configuration of
each tunnel have the parameter “Number of sessions to be compressed” configured
to less than 100.
Four Digit Virtual Port Number (Destination Subaddress)
Vanguard 7300 Series
The four digit virtual port number cannot be used as the destination subaddress. Only
three digit subaddresses are allowed. (DRCaa22259)
Workaround: The three digit Hunt Group must be used. If you need to target a virtual
port, that virtual port should have a unique Hunt Group value.
Software Image Naming Convention is Different - Alternate and Current
Vanguard 7300 Series
The software image naming convention is different for the Vanguard 7300 platform.
In the Vanguard 7300 platform, you are able to boot from the Alternate image and
the system shows that it was booted from Alternate. The Alternate image does not
become the Current image, as in the other Vanguard products. (DRCaa22270)
Note
When using the other (non-73xx) Vanguard products, when you boot from
Alternate, the Alternate image becomes the Current image.
Workaround: At present, there is no workaround.
Vanguard 7330 Power Supplies
When the Vanguard 7330 is configured with multiple power supplies, each power
supply shares the load. If a power supply should enter a failure condition, the second
power supply provides power for the entire system. Failure conditions can be
determined by viewing the LED on each power supply. Power supply fail conditions
are not reported as alarm conditions through the CTP menu or SNMP trap. The only
failure indication is the LED associated with the failed power supply. If one of the
power supplies fail, you will be operating in a non-redundant mode. (DRCaa22496)
Workaround: None. Periodically check the power supply LEDs.
