Description: < FOR cabletronELH100 Dual-Speed Hub DEFINITION : >
There are two kinds of hub :
12 ports need (1+ 12 + 1 + 1 + 1 + 1 +1 +1 +1) 20 bytes
and 24 ports need (1+ 24 + 1 + 1 + 1 + 1 +1 +1 +1) 32 bytes
The maximun size :
256 bytes (total for 8 hubs)=8 hub * (1+ 24 + 1 + 1 + 1 +1 +1 +1 +1) byte

A large read-only bitmask, up to 256 bytes, that packs link, collision, port-type, and switch/agent status for every port across all hubs in the stack into individual bits. Management software decodes it to render a stack-wide health/LED display rather than an admin reading it by hand.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.259.10.3.2.1.10 snmpwalk -v2c -c public <target> ELH100-MIB::stackHealthMonitor
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.259.10.3.2.1.10.1 snmpget -v2c -c public <target> ELH100-MIB::stackHealthMonitor.1
Start monitoring Cabletron ELH100 Ethernet hub/repeater with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the ELH100-MIB::stackHealthMonitor OID value, configure state conditions and alerts, and monitor any Cabletron ELH100 Ethernet hub/repeater from a single console.
