Page 36: Managing The Arp Table
You can use arp to modify the table for hosts that do not implement ARP, enabling communications between the host and the 5399 RAC. Using arp, you can delete a specified entry and/or create an entry for a host.
Page 37: Logging User And 5399 Rac Events
The security server logs each event as a message to its ACP log ﬁle. Security logging is enabled automatically when host-based security is enabled for an 5399 RAC (using the parameter enable_security). Events are logged to the security server that responded to the security request, either granting or denying access requests.
Page 38 Each logged message in the ACP log ﬁle can contain any of the following ﬁelds: For the 5399 RAC, the following additional ﬁelds are added: All ﬁelds are separated by colons (:) and are encoded for use by UNIX utilities that sort, merge, select, or ﬁlter streams.

Page 50: Monitoring Session Activity
Chapter 1 Network Administration Monitoring Session Activity The 5399 RAC provides two superuser CLI commands that display information about the state of the 5399’s serial ports: control and tap. The superuser CLI control command is a diagnostic tool that, for a specified port, allows you to set DTR and RTS or output a short test message.
Page 51: Managing The Host Table
If a DNS server recognizes the name, the entry is re-entered in the host table; otherwise, it is deleted. The 5399 RAC keeps track of how often each IEN-116 host table entry is referenced. If a name server entry has not been used for 32 days, it is deleted.
Page 52 60 minutes, the entry is removed from the table. If the host table acquires a new entry after it is full, the 5399 RAC deletes the oldest, least-used entry to make room for the new one. If the host table is too small, it frequently changes.

Page 54: Afd Status
Each 5399 RAC hardware platform provides a hardware installation guide that contains troubleshooting information. Many problems that occur after an 5399 RAC is running are due to improper conﬁguration of the 5399 RAC or a host. The following subsections describe the symptoms of several common conﬁguration problems.
Page 55: Hosts Not Appearing In Hosts Display
5399 RAC for either method of addressing by setting the broadcast_addr parameter. Wrong Host Address in Host Table The 5399 RAC assumes that the host described in the data part of the RWHO packet sent the packet, and the IP header’s source-Internet-address field contains the host’s address. Usually, this assumption is correct because routers do not forward broadcast packets.

An SNMP Network Management Station is a dedicated or shared network device that is the client in the client-server model. The management station can run an application speciﬁcally written for the 5399 RAC (or Remote Annexes) and its MIBs (e.g., Annex Manager), or a generic application that communicates with other non-Bay Networks devices (e.g.

Page 62 Chapter 2 Simple Network Management Protocol (SNMP) Deﬁning the Community String When an SNMP request is received by the agent in the 5399 RAC, the agent performs three tests to authenticate the request. The tests are as follows: The keyword community defines an SNMP community name from which the 5399 RAC responds to requests.

Page 64: Table B-16. Supported Snmp Traps
Traps are unsolicited administrative messages generated by SNMP agents on the network. The keyword traphost defines the host to which SNMP traps are sent. For the 5399 RAC to generate traps, one or more trap host addresses must be deﬁned in the gateway section of the configuration file along with the SNMP community string.
Page 65: Snmp Commands
The parameter disabled_modules allows you to turn off certain features during software initialization (e.g., enter LAT, PPP, SLIP to turn these features off). If you disable SNMP, the 5399 RAC will discard all SNMP messages it receives. By default, the SNMP agent on the 5399 RAC is enabled (for more details, see disabled_modules on page A-52).
Page 66: Table B-17. Supported Snmp Commands
SNMP set commands from IP hosts addreses and communities that have Read-write access permissions. When disabled, the 5399 RAC rejects all SNMP set commands; the 5399 RAC SNMP agent returns the error no such name for the ﬁrst object in the set command (for more details, see arap_v42bis on page A-41).
