Cisco is the major OEM in IT sector. In this categories, we will focus on configuring Cisco routers, switches, firewalls, wireless devices etc.
Today we will learn Best Practices for VPC on Cisco Nexus switches. Before going in deep, you should understand, what is vPC? Virtual Port-Channel (vPC) is a technology that allows links to be physically connected with two different devices to appear as a single port channel to a third device. You can read more from …
SNMP helps to gather and organize device information in an IP network. Currently, it has three main versions – v1, v2c, v3. The problem with the version v1 and v2c, there is almost no security. So, SNMP v3 was introduced to add security. Earlier, we have configured SNMP v2c, and today we will learn to …

Simple Network Management Protocol (SNMP) is an application layer protocol to collect and organize information about device in an IP network. In this lesson, we will learn to configure SNMP v2c in Cisco device. Pre-Check: Make sure port 161 is open for SNMP pulling from the device. And, also 162 need to be open to …

Policy Based Routing or PBR is a feature to manipulate routing and forwarding based on policies, set by the network administrator. In this lesson, we will learn to configure PBR in Cisco Nexus switches. Lab Diagram: Goal of the Lab: Create PBR for source PC-02 (192.168.1.11) Deny PBR for PC-02 when destination is 1.1.1.1 Existing …

DMVPN or Dynamic Multipoint Virtual Private Network is a tunneling protocol, which helps to build scalable IPsec Virtual Private Networks (VPNs). In this lesson, we will learn to configure DMVPN on Cisco router with single HUB. DMVPN is combine of- mGRE (Multipoint GRE allows a single interface to support multiple IPSec tunnel.) NHRP (Next Hop …

vPC failure scenarios are sometimes destructive. However, if you have good understanding on vPC and you follow Cisco recommended vPC design, then you can handle Virtual Port Channel (vPC) failure scenarios with confidence. In this lesson, i will be discussing different vPC Failure Scenarios, it’s impact on the network and how to solve the problem …

Virtual port channel (vPC) typically used for providing active-active connection from switch to end-point devices. However, due to it provide loop free design, we can configure one vPC domain on aggregation switches to other vPC domain on access switches while it providing more bandwidth for access switches to aggregation switches. This type of vPC called …
