32. Limitation 32
【Performance】On the same port of the board with suffixes B, it is suggested that
the number of delivered ACL configuration rules be no greater than 64. Otherwise, on
the port, forwarding speed cannot reach line speed.
33. Limitation 33
【Performance】Do not use regular expression in commands to check the system
configuration if the system has a large number of configuration items. For example,
the display current-configuration | include regular-expression command may cause
high CPU utilization, thus affecting packets exchange of the local device.
34. Limitation 34
【Board】Do not insert a 4-port 10GE board, such as XP4B, XP4CA, and XP4LDB,
into slot 1 or last slot in the S9512 frame, because these boards require higher heat
dissipation conditions.
35. Limitation 35
【 Board 】 XP4B and XP4CA do not support the following items: WAN mode,
aggregation, port isolation, traffic mirroring, traffic shaping, ACL issuing by VLAN.
36. Limitation 36
【Board】The GV48DB and GP48DB board cannot be used for the VLL (Virtual
Leased Line) with board intermixing, or the packets from the public network side will
be dropped, resulting in service forward failure.
37. Limitation 37
【Board】On the GV48DB and GP48DB board, an Access or Hybrid untagged port
cannot serve for mirroring source port; Otherwise, the mirrored packets may be
incorrectly tagged. As a result, some network adapters cannot identify the packets.
38. Limitation 38
【NetStream】NetStream does not create traffic flow entry for the first packet with the
TCP RST flag or FIN flag, and the system cannot take statistics about TCP RST
packets or FIN packets without corresponding traffic flow entries.
39. Limitation 39
【NetStream】In the case that there exist equal-cost routes or policy routes, the next-
hop, AS-number or interface may be incorrect in the NetStream statistics.
