Option1: If the current line cards installed support your PC/laptop’s 1GE UTP port, then you can install SFP-1000BaseT(SFP-T) transceiver directly to be used as the observing port. Fig.1 interface <interface name> port-mirroring inbound port-mirroring outbound port-mirroring to observe-index 1<1-255> interface <interface name> port-observing observe-index <1-255> Sample Configuration: Objective: To further do analysis on all traffic going to the Web server by port mirroring the interface going to the server. Port to mirror: Gi2/0/0 Port to observe:Gi1/0/0 <HW-Router>sys Enter system…

Here are the sample steps on finding the interface where the host is connected based on IP address or MAC address on Cisco Switch Nexus 7000 series running in Nexus OS. Scenario 1: IP address is given, find which interface it is connected IP address: 192.168.15.6 a. Find the routing entry for the IP to know where it is connected show ip route <IP> NEXUS7000# show ip route 192.168.15.6 IP Route Table for VRF “default” ‘*’ denotes best ucast next-hop…
Interface description is one of the most important configuration when bringing up interfaces between two devices. In a bundle or port-channel interface, there is a way to find the partner interface or which member in that bundle is your interface or port is connected especially if there’s no description or outdated. Here are the steps and commands to find LACP partner interface or port in Cisco Router and Switch Fig1.1 (Cisco IOS-XR) Assuming we have this Fig1.1, two…

As per Cisco documentation, Smart Call Home offers proactive diagnostics and real-time alerts on select Cisco devices, which provides higher network availability and increased operational efficiency. There are few ways on sending these alerts, it can be either by email or http. Sample Configuration using Email Method: callhome contract-id [value] switch-priority 7 email-contact [email-address] phone-contact [phone number] streetaddress [address] distribute destination-profile [PROFILENAME] destination-profile [PROFILENAME] format XML destination-profile [PROFILENAME] message-size [value] destination-profile [PROFILENAME] message-level 2 destination-profile [PROFILENAME] email-addr callhome@cisco.com destination-profile [PROFILENAME]…
As per Cisco documentation: A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus devices to appear as a single Port Channel to a third device. The third device can be a Cisco Nexus 2000 Series Fabric Extender or a switch, server, or any other networking device. A vPC can provide Layer 2 multipathing, which allows you to create redundancy by increasing bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative paths…
Link Aggregation Control Protocol or IEEE 802.3ad (LACP) is an open standard of Ethernet link aggregation protocol. It is a method used by routers/switches to automatically establish link aggregation groups or LAG ( sometimes called as channel groups, bundle or port-channels). Here’s LACP configuration examples for different Cisco platforms using LACP active mode, where it places a port into an active negotiating state and sending LACPDU (Data units) at regular intervals to seek out partners IOS (Catalyst 4500) Configuration: interface…
Objective: To configure port-channel and associate it to vlan. Servers will use Cisco-NXOS as their gateway and uplink to Internet. Server-switch have Layer 2 (access mode) connectivity to Cisco-NXOS router. (see Fig.1) Fig.1 1. Configure the Vlan (interface vlan will be the server’s gateway) Cisco-NXOS# configure vlan 8 name Server-Farm interface Vlan8 description Server Farm Vlan no shutdown ip address 192.168.8.1/24 2.
