What Is CISCOSB-IP?

CISCOSB-IP is a Cisco Small Business private MIB module that extends and mirrors the standard IETF IP-MIB for Cisco's small-business switch and router product line. It exposes IP addressing configuration per interface -- address, netmask, broadcast address, backup address, and administrative/row status -- along with references to related ICMP, RIPv2, and ARP specification objects, making it primarily a configuration and interface-status MIB rather than a hardware environmental one. Its monitoring value centers on interface/software configuration status: confirming which IP addresses are assigned and active (rsIpAdEntStatus, rsIpAdEntAdminStatus) on each interface, and cross-checking associated ARP/RIP behavior, which helps detect misconfigured or administratively-down IP interfaces on small-business gear. It is explicitly modeled on and dependent on the standard IETF IP-MIB, ICMP-MIB, RIPv2-MIB, and ARP conventions, adapting them into Cisco's private enterprise tree. It is deployed on Cisco Small Business series switches and routers, typically managed through Cisco's small-business web GUI or polled via SNMP by a lightweight NMS in small office/branch environments. Administrators tracing a specific CISCOSB-IP OID back to its parent object, such as rsIpAddrEntry, can quickly identify which interface and IP address entry it represents.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-IP. 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.

What Can Be Monitored

  • per-interface IP address assignment
  • subnet mask configuration
  • interface administrative/row status
  • broadcast and backup address configuration
  • ARP server setting per interface

Supported Devices

  • Cisco Catalyst 1200 Series (2022) — current SMB managed switch, successor to the Small Business 300 series
  • Cisco Business 350 Series — current managed switch for small business networks

Monitoring Examples

An administrator would poll rsIpAddrTable/rsIpAddrEntry to read rsIpAdEntAddr, rsIpAdEntNetMask, and rsIpAdEntIfIndex to verify the IP addressing assigned to each router interface, and check rsIpAdEntStatus/rsIpAdEntAdminStatus to confirm an interface is administratively up and its row is active. A device showing rsIpAdEntBackupAddr configured but the primary rsIpAdEntAddr unreachable could indicate a failover condition worth investigating, and rsIpAdEntArpServer settings help confirm ARP proxying behavior on that interface.

FAQ

How would an admin use CISCOSB-IP to confirm an IP interface is properly configured on a Cisco Small Business router?
By checking rsIpAdEntStatus and rsIpAdEntAdminStatus for a given interface, they can confirm the assigned IP address, netmask, and broadcast/backup address are active and administratively up, rather than administratively down or misconfigured.

What related protocols does CISCOSB-IP reference when troubleshooting IP interface issues?
It's modeled on and cross-references the standard IETF IP-MIB, ICMP-MIB, RIPv2-MIB, and ARP conventions, so an admin troubleshooting a misconfigured interface may also check the associated ARP server setting per interface and RIP behavior alongside the core address/status objects.
