Cisco Nexus 93180YC-FX Layer 3 Switch

What essential things to know for the switch settings?

Are you people planning for a new switch or router? Then it’s imperative to know the basic setting for configuration. Here in this blog, we will share some of the essential things to know for switch settings. Recently I came across the layer-3 switch, which was Cisco Nexus 93180YC-FX Layer 3 Switch and wants to include it in the network. So we have just gathered the basic things for all types of switch settings that we want to share with you. Have a look

Define default gateway

It’s essential to define the default gateway, which is easy to manage for the management IP and default gateway. It’s not easy to manage the overall device network with minimum and management IP address. Often, edge devices are provisioned where the IP address is configured, but the default gateway or default route is forgotten. Do you know what would happen when this configuration is missing? Without a default gateway or route of the network, the Cisco Nexus 93180YC-FX Layer 3 Switch is being utilized where traffic may reach the switch, but it’s unable to find the way back to the network. You won’t imagine how much edge devices are connected to the subnet, but often results are weird where switches become unmanaged.

Time setting

After basic IP settings, the next thing that comes to mind is time setting, where correct timing on switch is essential while troubleshooting the device. Mostly string of log entries is useless to network administrators while troubleshooting an issue. It’s pretty simple to set the time on the device. One of them is TimeP or Network Time Protocol (NTP), Simple NTP (SNTP). Make sure you all have a time server to keep all the networks in sync. No worries, if you don’t have a time server now, it’s effortless to add. Window server environments with a few clicks will make you up and running with SNTP in less than 5 minutes. Public time servers are best, although you don’t need to put all the switches over the internet for a time. Set time manually with every mean.

Activate the neighbour Protocols

It’s essential to activate the neighbour discovery protocols for network administrators and management tools to construct a network topology. Every manufacturer has a variant of neighbour discovery protocols. On using proprietary protocols, the two most widely used LLDP, IEEE standard and CDP. We observe in numerous devices that LLDP is supported for listening and talking, but CDP support is for listening. By simply enabling all supported neighbour discovery methods are highly recommended. Whatever information is provided allow you to locate neighbouring switches, and media endpoints such as phones and access point are connected. Get the detail of device type, its hostname, IP address and port, which is connected to the other end. All the network monitoring and management tools will use the protocols to crawl the network.

Configure logging and traps

Every notification on the network is a critical component for monitoring and troubleshooting the real-time alert. Most switches offer to send data to a central repository where logging events will be done via Syslog and trap events via SNMP. Configurations are pretty simple and varying minimally from switch to switch and from brand to brand. Many organizations have a Syslog server or a management tool to configure to receive SNMP traps simply. If your network doesn’t have an application, then investigate other options within budget. You can also look into existing management tools where you will find something you can use in production. You would get a variety of free Syslog and SNMP tools to ensure you will get free tools from various sources.

Add custom SNMP

This is used to manage or monitor all types of network devices, including switches, servers and desktops. SNMP enable the definition of different community strings, which is mapped over the other access points. We have two strings read-only and read-write string. The read-only string gathers information from the device. The read-write string allows management tools to make modification and configuration changes to the device. You would see switches have no predefined strings for a combination of public and private. It should be included with full management configuration, but within an organization, you will have a set or two of custom SNMP community strings, and these strings are not going to change from the time you order the switch. Just unbox it and deploy.

Network admins need to leave this out by figuring out how to get back to this. Management tools should be set using custom SNMP strings to start on the right foot by setting this early on the device. Just avoid the typos mistake to include these in the template. Incorrect SNMP strings are quite disturbing. Correct strings will let your device be seen and managed urgently with all monitoring applications.

These are the basic switch settings that everyone needs to know about settings. It would be a bit complicated, but if you people find this difficult, take help from the network administrator and make sure whatever switch is bought should be of high quality. CISCO CATALYST 3850-48XS-E – SWITCH – 48 PORTS switch by Cisco is one of the best choices so far and if you people are looking forward to buying anything else, then definitely opt for this. You won’t regret your choice.
