Using the Tcl shell to run CLI commands allows customers to build menus to guide novice users through tasks, to automate repetitive tasks, and to create custom output for show commands. Not everyone knows that it is possible to implement a port scanning tool like a light Nmap. Surfing the web I have found a tool named IOSMap, a Cisco port scanning tool.

Today I will explain how to monitor bandwith, CPU, &#8230; of routers and switches using SNMP and Cacti. Simple Network Management Protocol (SNMP) is an &#8220;Internet-standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more.&#8221; It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists [...]]]></description>

If your answer is negative, read how warm reload is faster than cold (classic) reload. Introduced in Cisco IOS Release 12.3(2)T, the warm reload feature allows users to reload their routers without reading images from storage. That is, the Cisco IOS image reboots without ROM monitor mode (ROMMON) intervention by restoring the read-write data from a previously saved copy in the RAM and by starting execution without either copying the image from flash to RAM or [...]]]></description>

IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite. It can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host).

		<description><![CDATA[Traceroute is a tool for measuring the route path and transit times of packets across an Internet Protocol (IP) network. Traceroute sends a sequence of Internet Control Message Protocol (ICMP) packets addressed to a destination host. Tracing the intermediate routers traversed involves control of the time-to-live (TTL) Internet Protocol parameter. Routers decrement this parameter and discard a packet when the TTL value has reached zero, returning an ICMP error message (ICMP Time Exceeded) to the sender. In a Data Center, it is often required to find a host and the layer2 path. To do it, Cisco has implemented a good [...]]]></description>

You can use another router! It is easy to do it. 1) Connect the console interface of the router/switch to the router aux interface using a rollover cable. Rollover cables essentially have one end of the cable wired exactly opposite from the other. As you can see below, this essentially “rolls over” the wires. 2) Configure the router aux interface with the transport input (in my example, I enable the telnet [...]]]></description>

		<description><![CDATA[Cron is a time-based job scheduler in Unix-like computer operating systems. The name cron comes from the word &#8220;chronos&#8221;, Greek for &#8220;time&#8221;. Cron enables users to schedule jobs (commands or shell scripts) to run periodically at certain times or dates. It is commonly used to automate system maintenance or administration, though its general-purpose nature means that it can be used for other purposes, such as connecting to the Internet and downloading email. What can I use to schedule a script or a command in Cisco? The kron feature Kron provides the ability to schedule some EXEC command-line interface (CLI) commands [...]]]></description>

The fastest solution is replace it with the &#8216;password recovery&#8216; (you can try to find the password with bruteforce attack but I think it is not the better solution..). During the password recovery procedure, it is fundamental sent the correct &#8216;Break&#8217; key sequence to enable ROMMON, but, as you know, the &#8216;break&#8217; sequence depends by the software that you use!

		<description><![CDATA[Do you remember the &#8220;Cisco regular expressions&#8221; tutorial? A regular expression is entered as part of a command and is a pattern made up of symbols, letters, and numbers that represent an input string for matching (or sometimes not matching). Matching the string to the specified pattern is called pattern matching. Pattern matching either succeeds or fails. If a regular expression can match two different parts of an input string, it will match the earliest part first. In this tutorial, I will explain how to use the &#8216;show&#8217; command with the regular expression. Below some examples: To check exactly an [...]]]></description>

		<description><![CDATA[The origins of regular expressions lie in automata theory and formal language theory, both of which are part of theoretical computer science. These fields study models of computation (automata) and ways to describe and classify formal languages. In the 1950s, mathematician Stephen Cole Kleene described these models using his mathematical notation called regular sets. The SNOBOL language was an early implementation of pattern matching, but not identical to regular expressions. Ken Thompson built Kleene&#8217;s notation into the editor QED as a means to match patterns in text files. A regular expression is entered as part of a command and is [...]]]></description>

		<description><![CDATA[VRF is an extension of IP routing that provides multiple routing instances. It provides a separate IP routing and forwarding table to each VPN and is used in concert with MP-iBGP (Multi-Protocol internal BGP) between provider equipment (PE) routers to provide Layer 3 MPLS-VPN. However, ML-Series VRF implementation is without MP-iBGP. With VRF Lite, the ML Series is considered a PE-extension or a customer equipment (CE)-extension. VRF Lite is considered a PE-extension since its has VRF (but without MP-iBGP), and it is considered a CE-extension since this CE can have multiple VRFs and serves many customer with one CE box.  [...]]]></description>

		<description><![CDATA[Working in a datacenter, it is often required to apply the same intereface configuration on many ports; Cisco has an embedded useful command to do it: the smartports macros. Smartports macros provide a convenient way to save and share common configurations. You can use Smartports macros to enable features and settings based on the location of a switch in the network and for mass configuration deployments across the network. Each Smartports macro is a set of CLI commands that you define. Smartports macros do not contain new CLI commands; they are simply a group of existing CLI commands.

An alias can be configured to do anything that can be done at the command line, but an alias cannot move between modes, type in passwords, or perform any interactive functions. To create a command alias, issue the alias command in global configuration mode. The syntax of the command is alias mode command-alias original-command.

The OSPF protocol is based on link-state technology, which is a departure from the Bellman-Ford vector based algorithms used in traditional Internet routing protocols such as RIP. OSPF has introduced new concepts such as authentication of routing updates, Variable Length Subnet Masks (VLSM), route summarization, and so forth. An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same [...]]]></description>

BGP is used to exchange routing information for the Internet and is the protocol used between Internet service providers (ISP). BGP is used between autonomous systems (AS), the protocol is referred to as External BGP (EBGP). If a service provider is using BGP to exchange routes within an AS, then the protocol is referred to as Interior BGP (IBGP).
