PACKET TRACER — BUILD A SWITCH AND ROUTER NETWORK

Packet loss under the same aggregation switch

Packet loss under the same aggregation switch

Verify LAG (Link Aggregation Group) of a Juniper Networks EX Series switch is UP and troubleshoot it if it is not. Port aggregation is useful for implementing load balancing and provides a redundant link backup. It enhances bandwidth, provides fault tolerance, and allows load balancing between connected devices. The following are the common causes for this type of issue: · Incorrect configuration on the aggregate interface.

Network packet loss after optical module malfunction

Network packet loss after optical module malfunction

Most instances of signal loss and intermittent link problems are caused either by declining optical power or a physical issue in the fiber path. There are multiple ways that optical modules fail in common ways that can interrupt network connectivity. PER Calculation: The Packet Error Rate (PER) refers to the ratio of the number of erroneously received packets to the total number of packets received. It also highlights how Digital Diagnostic Monitoring (DDM) and proactive testing techniques can help maintain optimal. Even tiny imperfections scatter or block light, causing signal loss (attenuation), errors (BER increase), or complete link failure.

How to check network loops on a core switch

How to check network loops on a core switch

You can test/check for network loops without disabling any ports by using Loop-Protect and setting the Receiver-Action to "no-disable". If one is detected, it will add an entry to the event log, but will not disable the port. A network loop occurs when redundant connections between switches cause data packets to endlessly circulate, suitable to broadcast storms, high CPU usage, and network congestion. Now at most of our sites we use Extreme, which has a handy feature called ELRP Extreme Loop Recovery Protocol, despite the name, this mechanism just detects loops, in the logs we can see, ok. The problem happening is that the core switch is disabling one uplink configured as a lag to one of the edge cabinets, when viewing the logs on the core, i found the below : LOOP DETECTION: VLAN 102, port lg110 detect, putting into err-disable state after disabling, reenabling the lag ports on the. There is also of course the way to get a hard proof by using Wireshark and a packet capture to check if one and the same frame is appearing with a.
