 -----------------------------------------------------------------------------



1. Limitations of the release MACH4002 09.1.12
==============================================
(01) The device can be managed by means of its agent's IP address as well as by
     those of its router interfaces.
     The agent's IP address must not be located in the same subnet of any of
     the router interfaces. If a router interface is assigned an IP address
     located in the agent's subnet, the agent's IP address will automatically
     be deleted.
     The agent's management VLAN ID must not be identical with any of the
     router interfaces' VLAN IDs. 
(02) VLAN based router interfaces are always displayed as operating at a
     speed of 10 Mbps. This has no effect on the router's real routing speed.
     However, in combination with OSPF, this may cause other paths being
     preferred in the routing decision. If this is not desired, the OSPF
     costs of a VLAN based router interface may be altered manually.
(03) SNTP multicasting (224.0.1.1) is not supported for router interfaces.
(04) IEEE-1588 is not supported for VLAN based router interfaces.
(05) It is not recommended to create more than 256 VRRP instances (virtual 
     router interfaces).
(06) If you enable IGMP support, IGMP snooping is also enabled. Generally it is 
     recommended to activate IGMP and IGMP snooping together.
(07) To activate multicast routing, you have to enable multicast forwarding, IGMP
     and a multicast routing protocol (PIM-DM or DVMRP) on a global basis and per
     router interface.
     This is necessary even if only one router is involved.
(08) You can only enable PIM-DM or DVMRP separately. The protocols cannot be run
     simultaneously.
(09) Routed multicasts are flooded over all ports of VLAN based router interface.
(10) If you change the prune/assert holdtime for PIM-DM, you should do this on all
     involved routers.
(11) From the software release 02.0.00 on, when prioritization via ACL
     (assign-queue) is used, frames are send with the modified VLAN priority. 
     This simplifies the system-wide prioritization. 
     Please note that IPv4 packets will also have their DSCP field modified:
     Assign Queue 0 -> User priority 0, DSCP:CS0 ( 0) 
     Assign Queue 1 -> User priority 1, DSCP:CS1 ( 8) 
     Assign Queue 2 -> User priority 2, DSCP:CS2 (16) 
     Assign Queue 3 -> User priority 3, DSCP:CS3 (24) 
     Assign Queue 4 -> User priority 4, DSCP:CS4 (32) 
     Assign Queue 5 -> User priority 5, DSCP:CS5 (40) 
     Assign Queue 6 -> User priority 6, DSCP:CS6 (48) 
     Assign Queue 7 -> User priority 7, DSCP:CS7 (56)
(12) From the SW Release 02.0.02, the RIP update interval is configurable (range
     1 to 1000 seconds). This can improve the RIP convergence time significantly.
     However, update intervals shorter than 10 seconds should be used only for small
     networks.
     Recommendation:
         Update interval:  1 sec. -> max. no. of routes: <=  250
         Update interval:  5 sec. -> max. no. of routes: <=  600
         Update interval: 10 sec. -> max. no. of routes: <= 1000
     The other RIP timers are set accordingly:
         Timeout           :  6 times the update interval
         Garbage Collection: 10 times the update interval
(13) In normal operating mode, packets that routed over VLAN router interfaces, are
     not sent with the VLAN router interface's MAC address as the source MAC
     address but with the physical port's MAC Address. This is compliant with the
     standard. Some terminal devices with incorrect IP implementation may have
     problems with that situation, resulting in them being unreachable via a VLAN
     router interface. For that reason, the SW Release 02.0.02 introduces the
     feature "Single MAC Mode". In this mode, all VLAN interfaces and all physical
     ports (except the port based router interfaces) use the same MAC address.
     It is recommended to use this "Single MAC Mode" only in combination with the
     setting "Independent VLAN Learning Switches".
(14) The Multicast Stream Detection (Handling of unknown multicasts)
     supports maximal 500 multicast addresses.
     If more addresses are used, the Multicast Stream Detection is switched off.
     The addresstable shows the unknown multicasts, that are detected by the
     Multicast Stream Detection.
     Non IP Multicasts are flooded always. 
(15) After replacing a media module with a media module of another type, 
	 check the settings of the corresponding ports and adapt the settings if necessary.
