Everyone knows there are software to get the configuration using SNMP; but how can you copy the configuration if you don’t have any tool? Let me explain what is SNMP before show you how to implement it. Simple Network Management Protocol (SNMP) is an “Internet-standard protocol for managing devices on IP networks”. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP uses an extensible design, where the available information is defined by management information bases (MIBs). MIBs describe the […]

The Cisco Product Security Incident Response Team (PSIRT) has published two important vulnerability advisories: Cisco TelePresence Supervisor MSE 8050 Denial of Service Vulnerability Multiple Vulnerabilities in Cisco Unified Customer Voice Portal Software Cisco TelePresence Supervisor MSE 8050 Denial of Service Vulnerability Cisco TelePresence Supervisor MSE 8050 contains a vulnerability that may allow an unauthenticated, remote attacker to cause high CPU utilization and a reload of the affected system. Vulnerable Products Cisco TelePresence Supervisor MSE 8050 running software versions 2.2(1.17) and earlier are affected by this vulnerability.
Do you remember the article ‘How to schedule a reload‘? This feature (reload in ‘x’) is useful when you must apply a critical configuration on a remote device, for instance new route or new acl. In fact, if you happen to lose connection to device after a change, you must wait the device reload to reconnect to it. This can be a solution but there is a better solution: the replace/roolback feature. Introduced in 12.3(7)T IOS, the Configuration Replace and Configuration Rollback features provide the capability to replace the current running configuration with any saved Cisco IOS configuration file. This […]
Cisco IP SLAs is a part of Cisco IOS that allows Cisco customers to analyze IP service levels for IP applications and services by using active traffic monitoring for measuring network performance. With Cisco IOS IP SLAs, service provider customers can measure and provide service level agreements, and enterprise customers can verify service levels, verify outsourced service level agreements, and understand network performance. Cisco IOS IP SLAs can perform network assessments, verify quality of service (QoS), ease the deployment of new services, and assist with network troubleshooting. IP SLAs collects a unique subset of these performance metrics: Delay (both round-trip […]

Everyone knows that the routing table lists the routes to particular network destinations, but is it possible define the next-hop based on source ip, packet size or other criteria? Obviously yes! Policy-based routing (PBR) provides a tool for forwarding and routing data packets based on policies defined by network administrators. In effect, it is a way to have the policy override routing protocol decisions. Policy-based routing includes a mechanism for selectively applying policies based on access list, packet size or other criteria. The actions taken can include routing packets on user-defined routes, setting the precedence, type of service bits, etc.
