Overview

Welcome to our comprehensive technical support FAQ for enterprise-grade 10G core switches. This guide directly addresses the most common pre-sales sizing concerns and post-sales operational challenges faced by network architects and procurement specialists. For partners looking to streamline deployment, we highlight a critical service: the ability to pre-load your custom ISP configuration firmware into OEM devices before shipping, ensuring your network is ready to route from the moment it is powered on. We cover everything from maximum backplane throughput and optical transceiver compatibility to advanced CLI stacking protocols and redundant power failover mechanisms.

Frequently Asked Questions

Q1: Can you load our custom ISP configuration firmware into OEM 10G core switches before shipping?

Yes, we can pre-load your custom ISP configuration firmware onto all OEM 10G core switches prior to global shipment. Our factory provisioning process includes a dedicated staging area where we upload your proprietary OS images, VLAN setups, and ACL policies, followed by a rigorous 24-hour burn-in test to verify stability under load. This ensures your hardware arrives fully configured, reducing onsite deployment time to just racking and cable connection.

Q2: What is the maximum switching throughput and backplane capacity of this 10G core switch?

The maximum switching capacity is 2.56 Tbps with a forwarding performance of up to 1,920 Mpps for 64-byte packets. This line-rate capability is driven by a fully non-blocking architecture and a shared 32MB packet buffer, ensuring zero packet loss during micro-burst traffic scenarios typical of high-density spine-leaf datacenter designs.

Q3: What is the difference between this 10G core switch and previous generation 1G aggregation switches?

Unlike previous 1G aggregation models, this 10G core switch offers a 10x increase in port bandwidth and supports advanced Layer 3 routing protocols (OSPF, BGP, and VRRP) at hardware-level speeds. Crucially, it features a modular hot-swappable power supply and fan tray design, whereas the previous generation required full chassis downtime for replacement, making this model superior for high-availability core backbones.

Q4: What is the maximum number of stacking interfaces supported, and how do I troubleshoot stacking errors?

The maximum stacking interface support includes 2 x QSFP+ stacking ports per unit, allowing for a virtual chassis of up to 8 switches (128 x 10G ports) with 120 Gbps of stacking bandwidth. To troubleshoot stacking errors, first check the priority settings and verify the dedicated stacking cable quality; you can also use the 'show switch stack-ports' CLI command to identify a malfunctioning member and preemptively renumber it before the master election timeout occurs.

Q5: How do I troubleshoot a redundant power supply failover on the 10G core switch?

To troubleshoot power failover, begin by verifying that both AC/DC modules are plugged into independent circuits and that the 'redundancy mode' is set to 1+1 in the boot environment. If failover occurs, check the system logs for voltage sag alerts; the switch automatically engages the backup within 10ms, but if this fails, a manual reboot of the faulty module is required after checking the fuse status, followed by the command 'set power-supply slot 2 enable'.

Q6: Which optical modules are compatible with the SFP+ and QSFP ports for 10G and 40G uplinks?

This 10G core switch is universally compatible with MSA-compliant SFP+ modules for 10G connections (SR, LR, and ER) and QSFP+ modules for 40G uplink aggregation. For optics, we recommend using digital diagnostic monitoring (DDM) enabled modules to track temperature and voltage; however, third-party optics are fully supported provided you disable the 'vendor-check' global command in the global configuration mode.

Q7: What is the basic CLI configuration process for initial setup after unboxing?

The initial CLI setup process involves connecting to the console port at 115200 baud, using the 'enable' command to enter privileged mode, and configuring the out-of-band management IP. The standard workflow is to set the hostname, assign the default gateway, and apply a password encryption policy; this is followed by the 'copy running-config startup-config' command to secure the changes, ensuring your management interface is online and secure.
