HP Hub-12TX/Hub-12TXM Installation and Reference Guide
Product Overview 1-3
The specific components are the:
Hub-12TX
Fast Ethernet Stackable Hub with 12 100Base-TX Ports
The Hub-12TX conforms to the IEEE 802.3u hub specification. It
also collects port statistics and records events for system
administration. Basic configuration is provided by the VT-100
console interface.
This hub can be used in a standalone configuration to form a
simple LAN networking two to 12 computers using the RJ-45
hub ports.
Moreover, when stacked with other hubs through the Stacking
Ports and connected to an SNMP management device (e.g., the
Hub-12TXM), it can be monitored and controlled through in-band
or out-of-band channels.
Two to five hubs can be stacked and connected together with the
Stacking Cable, each additional hub correspondingly increasing
the stack’s collision domain. Just one Hub-12TXM placed in a
stack is sufficient to manage all other hubs.
Hub-12TXM
Fast Ethernet Stackable Hub with 12 100Base-TX Ports; including SNMP
Management Support
This model conforms to both the IEEE 802.3u hub specification
and the Simple Network Management Protocol (SNMP). It not
only functions as a 12-port Fast Ethernet hub, but also provides
an SNMP-based network management agent for monitoring and
controlling various network components. It can monitor up to
five hubs connected to the same stack (including itself) through
the Stacking Port connection. This hub provides SNMP
management for the connected stack via various Management
Information Bases (MIBs), including MIB II, several hub MIBs,
and a private MIB.
