Book B Chapter 1
Network Administration
This chapter discusses typical software configuration procedures as
wellas network administrationusing Annextools and utilities. Usingthe
Annex, you can:
• Monitor network activity.
• Monitor Annex activity.
• Secure the network.
• Manage the Annex’s host table.
Monitoring Network Activity
The Annex provides three CLI commands (netstat,ping, and arp) to
monitornetworkactivity (formoredetails, seeUsingtheCLI Commands
on page A-121). Using the CLI commands, you can:
• Display network statistics.
• Test the network.
• Manage the ARP table.
Displaying Network Statistics
The CLI netstat command displays information that the Annex has
obtained from the network. Using netstat you can display:
• Active connections.
• Ethernet statistics.
• PPP statistics.
• SLIP statistics.

• Routing table information.
• Route cache information.
• Dial-out route statistics.
• Rotary information.
• Filtering statistics.
• Memory statistics.
• Protocol statistics.
Active Connections
Entering the netstat command without arguments displays the local and
remote addresses, send and receive queue sizes (in bytes), protocol, and
theinternalstateoftheprotocolforallactiveconnections.Table B-1lists
the arguments for this command.

Statistic Description
Frames Received The number of packets received from the network
interface.
Frames Transmitted The number of packets transmitted on the network
interface.
Bytes Received The number of bytes received from the network
interface.
Bytes Transmitted The number of bytes transmitted on the network
interface.
CRC Errors The number of frames received from the network
interface with a bad CRC.
Alignment Errors The number of frames received from the network
interface that were both misaligned and have a CRC
error.
Bad Type/
Length Fields The number of frames received from the network interface that have an unrecognized type field
(ethernet) or an illegal length field (802.3).
Buffer Drops The number of frames received from the network
interface that were good, but dropped because no
buffers were available.
FIFO Drops The number of frames received from the network
interface that were lost since the local system bus was
not available.
Interface Resets The number of times the network interface has been
initialized from reset; typically, one.
TX DMA
Underruns The number of times a frame transmission is terminated due to lack of data.

Statistic Description
RX DMA Overruns The number of times a frame reception is terminated
due to lack of system bus bandwidth.
Carrier Sense
Losses The number of times a frame transmission is terminated due to loss of the Carrier Sense signal. The
transceiver cable may have a short or an open.
Clear to Send
Losses The number of times a frame transmission is terminated due to loss of the Clear to Send signal.
Collisions Detected The number of times a frame transmission is
terminated due to a collision.

AppleTalk Statistics
The netstat –i command displays interface statistics. AppleTalk
addresses display as net.node in hexadecimal, where net is 16 bits and
node is 8 bits. ARAP interfaces display as ara plus the unit number.
Table B-4 defines the arguments for displaying AppleTalk statistics.

Field Definition
Intf Displays the interface.
Bad Pkts Displays the number of packets the interface dropped due to
invalid format or data.
Bad Rtes Displays the number of routes the interface dropped due to
invalid format or data.
Trigg. Displays the number of triggered updates transmitted over
the interface. The Annex sends triggered updates whenever it
changes the hop count of a route. It transmits them
immediately, even if it is not yet time for one of the regular
update messages to be transmitted.
Rec’d Displays the number of packets (with or without errors)
received over the interface.
Sent Displays the number of output packets the Annex tried to
send over the interface. This number includes packets that
were dropped because the Annex ran out of buffers or the
link’s output queue was full.
Disc’d Displays the number of input packets discarded due to
protocol errors or restrictions set by configuration
parameters (e.g., rip_accept).
Update Displays the number on lines in the routing table that were
modified due to packets received on that interface.
Queries Displays the number of routing-table queries received on the
interface.
