Hitachi Gigabit Router GR2000 Series Enhanced Version Configuration Commands, Vol. 2

Ver. 07-02
4. -cops_range cannot be set when flow filter and flow qos list numbers that have
been already used exist in the range of the specified list number.
5. A -cops_range parameter in which the number of RP unit entries exceeds 2000
cannot be set.
6. The -cops_range parameter of this command cannot be deleted when COPS
configuration definition is set.
7. The setting of a cops_range parameter cannot be changed and deleted when a
COPS function operates and when the information set from the policy server
exists in this router. Delete the information set in this router from the policy
server and then change or delete the -cops_range parameter.
8. If a condition persists in which the interface that set the flow filter and flow qos
on the outbound side does not restore after overloading, the following message is
displayed and RP or NIF may restart. Design the system using the relaying
performance value shown in the table as reference.
RP hardware failure has been detected.
NIF has been restarted because of NIF hardware
failure.(xxisanindicationofsevensegments,andvvisanoptionalvalue.)
9. For the IPv6 packet produced by this device, control is given in accordance with
the priority set in the
flow qos command regardless of the presence of "-classify
all" parameter.
10. Flow information consumes 101 entries in each RP when address conversion
(nat) is set. Therefore, when address conversion (nat) is set, the maximum entry
count is decreased by 101 per RP capable of flow information definition.
1.1.4 flow filter (Filter Flow Information)
The filter flow information (filter condition to relay or discard a packet) is set. This
command allows the preparation of a filter list concerning the IPv4 and IPv6 packets.
Respective filter lists are decided by the list number described later.

*1: Values in the table show the use rate of lines accommodated in one RP compared to the total band. There should
be no problems in other combinations.
*2: RP-A1 can be set to a maximum of 1024 entries. If the communication is not restored after restarting the device,
introduce the "close rp" command/"free rp" command in order to re-actuate the applicable RP. Refer to the GR2000
Operations Commands, Vol. 1, close up and free up commands, respectively.
