40. Limitation 40
【NetStream】Packet statistics log transmission is delayed because the statistics
information is collected by the NetStream board every a specified interval.
41. Limitation 41
【NetStream】The NetStream board does not support collecting statistics of MPLS
traffic by labels on the outgoing interface at the public network side when the S9500
functions as a PE.
42. Limitation 42
【NAT】In NAT multi-instance networking, the NAT log server cannot function at the
private network side, and VPN users at the private network side have to obtain filtered
VPN log information through service provider.
43. Limitation 43
【NAT】If a private network has an internal server configured with NAT, the IP
address of the server may be exposed when a user directly connecting to a VLAN
interface of the public network without NAT accesses the internal server.
44. Limitation 44
【NAT】A new traffic flow entry may not be able to set up for a short period when
aged ports in NAT traffic flow table are recalled. It may cause packet loss while NAT
tries to create a new traffic flow entry.
45. Limitation 45
【Upgrade】It is required to load the BootROM upgrade file to the Flash memory
before you upgrade the BootROM version of the MPU through BootROM menu.
Otherwise, BootROM upgrade file may not be specified during the upgrade process.
46. Limitation 46
【Upgrade】 BootROM upgrade may be failed if the BootROM file name (including
path) exceeds 56 characters.
47. Limitation 47
【RPR】Class A packet congestion on GE RPR may affect the forwarding of Class C
packets, because two sub-rings of a GE RPR share the same back pressure
signaling, and one sub-ring's back pressure signal may be applied to the other sub-
ring.
