IP Set Router-ID

Sets the default IP address used by the router when sourcing various IP packets. This address is of particular importance in multicasting and OSPF.

For example, the source address in pings (including multicast pings), traceroute, and TFTP packets sent by the router is set to the router ID. In addition, the OSPF router ID for this router is set to the configured router ID.

Note: Configuring a router ID may cause the router's OSPF router ID to change. If this happens, link state advertisements originated by the router before the router ID change persist until they age out - possibly as long as 30 minutes. This may cause an increase in link state database size.

The router ID must match one of the configured IP interface addresses of the router or the configured internal IP address. If not, it is ignored. When ignored, or just not configured, the default IP address of the router (and its OSPF router ID) is set to the internal IP address (if configured) or to the first IP address in the router's configuration.

Enter the address to be used for the router.

Valid Values: any valid IP address

Default Value: none

IP Set Tag

Configures the interface tags associated with received RIP information. These tags can be used to group routes together for later readvertisement via BGP where a tag will be treated as if it were a route's source autonomous system (AS) number.

Enter the interface tags.

Valid Values: an integer in the range of 0 - 65535

Default Value: 0

Select the Submit button.


IP Set TTL

Specifies the time-to-live for packets originated by the router.

Enter the time-to-live.

Valid Values: a numeric in the range of 1 - 255

Default Value: 64

Select the Submit button.


IP Move Access-Control

Use the Move Access Control option to change the order of records in the global access control list. This command places the first access record identified just after the second access record identified. After you move the records, they are immediately renumbered to reflect the new order.

The router applies the access control records in a list in the order in which they were created. For each packet received on an interface, the router applies each access control record in order until it finds a match. The first record that matches the packet determines whether it will be discarded or forwarded to its destination.

This makes the order of the access control records very important. If they are in the wrong order, certain packets may slip through, or be blocked, in a manner contrary to your intentions.

If for example, that access control record 1 enforces the rule: All packets from network 10.0.0.0 shall be blocked on this interface.

Contrary to this, access control record 2 states: Packets from subnet 10.5.5.0 in network 10.0.0.0, which are destined for address 1.2.3.4, shall be allowed to pass.

Assigned in this order, these records will block all traffic from 10.0.0.0, even though record 2 explicitly allows certain types of packets to pass, and record 1 disables record 2.

To correct this type of problem, you can change the order of the access control records. In the example, you can move record 2 in front of record 1. This way, packets in subnet 10.5.5.0 and destined for address 1.2.3.4 will pass through the interface; the router discards all other packets from 10.0.0.0 as intended.

Use the list command to obtain the following index numbers to enter.

  1. Enter index of access control to move.

  2. Enter the Move record AFTER record number.

Select the Submit button.

  6. Enter the starting protocol number and ending protocol number.

    This protocol number range is compared with the protocol byte in the IP header of each received IP packet. Each IP packet with a protocol value within the specified range will be forwarded. A range of 0 to 255 matches all IP packets.

    The commonly used protocol numbers are:

    See RFC 1340, "Assigned Numbers" for details on IP protocol numbers.

    Valid Values: 0 to 255

    Default Value: 0

    These valid values and default apply to starting protocol number and ending protocol number.

Add ARP Server Private-NSAPA

Adds an ARP server to the client specified. Only one ARP Server is allowed per client. During initialization, the specified Classical IP client will place a call to the ARP server, and will use it as the mechanism for resolving IP addresses to ATM addresses.

If a CIP client is configured to also be a server, then this option will override the client configuration and the client goes to the remote ARP Server to resolve all addresses.

  1. Enter the local client IP address.

    Valid Values: any valid IP mask

    Default Value: none

  2. Enter the Private NSAP (ATM) address.

    Valid Values: any valid ATM address with the first byte as follows:

    The Private Network Specified Access Point (NSAP) Address is the addressing format specified in the UNI versions 3.0 and 3.1. The first byte of the address defines the addressing format, as follows:

    First Byte
    NSAP Address Format Specification
    0x39
    DCC ATM Format
    0x47
    ICD ATM Format
    0x45
    E.164 ATM Format

    Note: This setting corresponds to a client's (IP address/port number) pair.

    Default Value: none

Select the Submit button.


Add ATM ARP Client Configuration

Adds ATM ARP client configuration.

You will be prompted for the following information.

Note: Any bandwidth or cell parameter that equals zero will be treated as the line speed of the ATM interface.

  1. Select the Interface Number.

  2. Select the protocol that is to be used on the interface

    Choose IP or IPX.

  3. If you select IP, then enter the Client IP Address.

    Valid Values: any valid IP address

  4. Select the Submit button.

  5. Answer yes or no to the question, This client is also a server?

    When the client is configured to also be a server, both functions share the same ATM address.

    Both the CIP client and ARP Server age their ARP entries. Once the timer expires, these ARP entries are deleted. The Refresh Timeout value is the length of time that an ARP entry will be kept before aging out.

    If traffic is flowing when an ARP entry gets aged, that traffic will cease for a period until a new ARP entry is created. To avoid an interruption in service, use the automatic refresh option. This option allows the client to transmit either an ARP to the ARP Server or an InATMARP to the target client some time before the ARP entry expires. If the target replies, then the timer of the ARP entry is reset. If the target does not, then the entry is deleted. The ARP Server automatically sends out an InATMARP message before aging an entry in its table.

  6. Enter a Refresh Timeout value.

    Valid Values: an integer number of minutes in the range of 0 - 65,535

    Default Value: 5 minutes

  7. Enable auto-refresh

    This parameter specifies whether an ARP Request will be sent to the ARP Server or an InATMARP Request will be sent to the client immediately before an ARP entry is aged out.

    Enabling auto-refresh could cause entries to be retained in the cache regardless of their usage. On networks with a large number of nodes, this can lead to an excessive number of entries in the cache, which might adversely affect device performance. However, on networks with a small number of nodes, this option is useful in reducing broadcast ARP traffic.

    Valid Values: Yes or No

    Default Value: No

  8. Answer yes or no to the question Refresh by InAtmArp?

    If Yes, and if auto-refresh is enabled, then InAtmArp requests will be periodically transmitted to confirm the existence of the remote host. If No, then AtmArp requests will be transmitted to the ARP Server to reconfirm the ARP entry.

  9. Select ESI

    Select the ESI index number from the scrolling list. (the list of configured ESIs that you previously configured using the Add ESI network configuration option).

    Default Value: Burned In

  10. Answer yes or no to the question Use internally assigned selector

    If you answer yes, an automatically generated value will be used as the selector component of the ATM address.

    If you answer no, then you should enter a selector value.

    Valid Values: any single octet value that has not been previously used and is within the range defined for the device.

    Default Value: none

  11. Validate PCR for best effort VCCs

    Valid Values: Yes or No

    When yes, Best-Effort VCCs will be rejected if the signaled forward PCR exceeds the Maximum Reserved Bandwidth or the speed of the adapter.

    If no, Best-Effort PCRs will be rejected without regard to the signaled Peak Cell Rate.

    Enter a Maximum Reserved Bandwidth for incoming VCCs (Kbps)

    This value defines the maximum acceptable Sustained Cell Rate (SCR) for an incoming VCC.

    Valid Values: Specify an integer in the range of 0 to the line speed of the ATM device.

    Default Value: 155000 Kbps

    If SCR is not specified on the incoming call, then this parameter defines the maximum acceptable Peak Cell Rate (PCR). Calls received with traffic parameters specifying higher rates will be released. This parameter is applied to both forward and backward Cell Rate parameters.

    The constraint imposed by this parameter is applicable to best effort connections (if "validate PCR" is yes) and is compared to the PCR on the incoming call.

  12. Use Best Effort Service for Control VCCs

    Specifies the type of traffic characteristics to be associated with Control VCCs.

    Valid Values: Best Effort or Reserved Bandwidth

    Default Value: Best Effort

    Bandwidth is not reserved for best effort traffic.

  13. Peak Cell Rate of outbound control VCCs (Kbps)

    Specifies the Peak Cell Rate (PCR) traffic parameter for the Control VCC. This PCR value is used for both the forward and backward PCR values of both best effort and reserved bandwidth VCCs.

    Valid Values: an integer Kbps in the range of 0 - line speed of the ATM device

    Default Value: If Best Effort VCC, then default is 155000. Otherwise, no default is provided.

  14. Sustained Cell Rate of outbound control VCCs (Kbps)

    Specifies the bandwidth reserved by all VCCs on a given ATM device. (Sustained Cell Rate can be considered to reserved bandwidth.)

    Valid Values: an integer Kbps in the range of 0 - control VCC PCR

    Default Value: none

    This parameter is applicable only when Best Effort Service is not selected for Control VCCs.

  15. Use Best Effort Service for Data VCCs

    Specify Yes or No. This parameter specifies the type of traffic characteristics to be associated with Data VCCs. Bandwidth is not reserved for best effort traffic.

  16. Peak Cell Rate of outbound Data VCCs (Kbps)

    Specifies the Peak Cell Rate (PCR) traffic parameter for the Data VCC. This PCR value is used for both the forward and backward PCR values of both best effort and reserved bandwidth VCCs.

    Valid Values: an integer Kbps in the range of 0 - line speed of the ATM device

    Default Value: If Best Effort VCC, then default is 155000

    Otherwise, no default is provided.

  17. Sustained Cell Rate of outbound Data VCCs (Kbps)

    Specifies the Sustained Cell Rate (SCR) traffic parameter for the Data VCC. (Sustained Cell Rate can be considered to reserved bandwidth.) This parameter is applicable only when Best Effort Service is not selected for Data VCCs.

    Valid Values: an integer Kbps in the range of 0 - PCR value for Data VCC

    Default Value: none

  18. Max Service Data Unit (SDU) size (bytes)

    Specifies the Maximum SDU size that will be specified when calls are placed from this client address. It also is used to verify incoming calls. This parameter cannot be set to a value greater than the Maximum SDU size for the physical ATM interface (port).

    Valid Values: an integer in the range of 72 - Maximum interface SDU

    Default Value: 9188

  19. Click to indicate whether this configuration, if a server, is participating in server synchronziation. Answering yes to this question indicates whether the ARP database for the LIS upon which this server resides will be distributed.

  20. If this is a server, enter a Server group ID.

    Valid Values: 0 - 65535

    Default Value: 1

  21. Click to indicate if this server will Accept sessions from a non-configured Directly Connected Server.

  22. Enter a Hello Interval. This value specifies the time in seconds between sending of Hello messages for the local server.

    Valid Values: 0 - 65535

    Default Value: 3
