Description: H3C MIB for configuring and monitoring Access Control Lists (ACLs) including rules, groups, and match statistics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is H3C-ACL-MIB?

H3C-ACL-MIB is an H3C (Hangzhou H3C Tech.) vendor-specific MIB (under the HUAWEI-3COM-OID-MIB h3cCommon subtree) that configures and monitors Access Control Lists across H3C switches and routers, supporting both link-based and IP-based ACL modes (h3cAclMode). It organizes rules into numbered groups (h3cAclNumGroupTable, ranges reserved per ACL category) or named groups (h3cAclNameGroupTable), with per-rule match criteria split across h3cAclBasicRuleTable (source IP/wildcard, fragments, time-range), h3cAclAdvancedRuleTable (protocol, source/destination IP and Layer 4 ports with operators like lt/eq/gt/range, DSCP/TOS/precedence, ICMP type/code, TCP-establish flag), h3cAclIfRuleTable (interface-based matching), and h3cAclLinkTable (Layer 2 matching on MAC addresses, VLAN tags, Ethernet type, and even MPLS label ranges/EXP bits for link ACLs). Each rule table exposes an Enable flag showing whether the rule is currently active, a matched-packet Count counter with a CountClear reset control, and a RowStatus for CreateAndGo/Active/Destroy lifecycle management. Because ACL rules directly gate forwarding, this MIB is deployed on H3C devices doing traffic filtering and security policy enforcement, and administrators download the H3C-ACL-MIB file to poll match counters and confirm that critical ACL rules remain active.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-ACL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • H3C switches and routers

Monitoring Examples

An operator polls h3cAclAdvancedCount for a rule in h3cAclAdvancedRuleTable while confirming h3cAclAdvancedEnable is true, and a rule that shows enable=false or a stalled counter despite expected matching traffic would indicate the ACL rule was deactivated or superseded by a higher-priority rule.

What Can Be Monitored

  • numbered/named ACL group configuration
  • basic/advanced/interface/link rule match criteria
  • per-rule matched-packet counters
  • rule active/enabled status
  • row status lifecycle of ACL entries

How to Use in IPNetwork Monitor

Example using h3cAclBasicCount OID:

Select an H3C switch/router (Access Control Lists) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type h3cAclBasicCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The count of matched by basic rule. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
