SNMP
The 8239 contains an SNMP agent that can communicate with an SNMP manager.
The following MIBs are supported by the 8239:
IBM 8239 TR Hub MIB
RMON (RFC 1757)
TR Extensions to RMON (RFC 1513)
RMON 2 (RFC 2021)
RMON MIB Protocols IDs (RFC 2074)
Aspen Config MIB
Trapmib
DLM Mib
ECAM MIB
IEEE 802.5 TR MIB (RFC 1748)
IBM TR Surrogate MIB (AWP-7607)
IBM TR Surrogate Trap MIB (AWP-7607)
MIB II (RFC 1213)
All MIBs supported by the 8239 can be accessed via the 8239 Model 1’s IP
address.
PING
PING is a useful starting point for verifying connectivity or diagnosing network
problems. Use it to test the reachability of IP devices on the network. The 8239
supports:
¹
Pinging from the 8239 Model 1 to another IP address
¹
Pinging from an external token-ring station to the 8239 Model 1’s IP address
Issuing the PING command at the 8239 terminal prompt results in the 8239 sending
10 Internet Control Message Protocol (ICMP) request packets to the specified
device. If the device is active, it should respond to each request packet from the
8239. If the device responds to less than 100% of the request packets, the network
may be dropping packets.
If you have trouble pinging a remote device, make sure that:
¹
The 8239’s IP information (IP address, subnet mask, and default gateway) is
correct
¹
The device is on the same network (segment), or bridged or routed to that
segment
¹
The Management Interface is enabled (using the SET
MANAGEMENT_INTERFACE ADMINISTRATIVE_MODE command
¹
Use the SET MANAGEMENT_INTERFACE ARP_RESOLVE_METHOD
command to clear the source routing bit in Address Resolution Protocol (ARP)
packets
TFTP
Use the Trivial File Transfer Protocol (TFTP) to transfer files to or from the 8239
Model 1. These types of files can be transferred
to an 8239 Model 1:
¹
Code
¹
Configuration setup files
¹
Scripts
