Cisco Nexus 7000 Sequential and Parallel EPLD Upgrade. Who wins?

Whether it is a fresh new install or a software upgrade, these would be the time for you to also consider an EPLD upgrade. Unlike software upgrade where you can potentially avoid an extended downtime using In-Service Software Upgrade (ISSU), EPLD upgrade requires the hardware to be taken offline and, in some cases, even chassis reload. Since the EPLD version has to stay in sync with the NXOS version, depending on what version you are upgrading to, you might need to upgrade all the pieces of hardware, and these include all supervisors, linecards, fans, and fabrics, which can result in a significant downtime.

In this article, we will provide timing results from running tests between sequential and parallel EPLD upgrade. This is to give you some guideline and help you determine appropriate actions for your environment.

What You Need to Know About Cisco Nexus 7700 Switch

Cisco has recently released a new datacenter switch product family: Nexus 7700. For those of you who are already familiar with Nexus 7000 and wondering about their similarities and differences, here are the quick rundowns on Nexus 7700.

SEC0064 - Introduction to VSG and VNMC

The video introduces you to the concepts behind Cisco VSG and VNMC. We will help you understand how VSG works with other components such as VNMC, VSM and VEM to provide policy-based security within an IP subnet. This video serves as a prerequisite to our future VSG labs. Since this is an introduction-to-technology video, there will be no lab.

Topic:
  • VSG
  • VNMC
  • VSM
  • VEM
  • vPath

RS0034 - Nexus 1000V VXLAN

The video looks into Virtual Extension LAN (VXLAN) support on Cisco Nexus 1000V. VXLAN allows VLAN ID to be extended to 24 bits, or in other words, essentially increases number of available VLAN from 4096 to more than 16 million VLAN. We will configure VXLAN on port-profile. In this lab, we intentionally have VEM control interfaces separated by layer 3 to demonstrate MAC-in-IP encapsulation provided by VXLAN to extend an isolated layer 2 domain across a routable and multicast-enabled network.

RS0033 - Nexus 1000V Cisco TrustSec with ASA 9.1

The video looks into Cisco TrustSec feature on Cisco Nexus 1000V. We will configure port-profiles to assign SGT to hosts, and have SGT-to-IP mapping sent to an ASA firewall over a SXP connection for policy enforcement. We will see how we can construct an ACL on the ASA to permit or deny traffic based on SGT value using a object-group-security.

RS0032 - Nexus 1000V Private Vlan

The video looks at how we can achieve network separation at layer 2 with private vlan on Cisco Nexus 1000V. We will go through the concept of Primary, Secondary, Isolated and Community VLANs, and experiment with server communication by placing the servers on different vlan. At the end of the video, we will also go through a scenario where we have two sets of private vlan. Private VLAN allows hosts to remain segregated on the same IP subnet.

RS0031 - Nexus 1000V QoS

The video presents three main QoS building blocks on Cisco Nexus 1000V: Marking, Policing, and Queuing. We will be applying QoS to Port-Profile to mark RDP traffic, and enforcing policing based on matching DSCP value. Any traffic exceeding allowable rate will be either drop or marked down. We will attempt to provide guaranteed bandwidth to both Nexus and VMware control traffic. DSCP values will be analyzed using Wireshark packet capture.

RS0030 - Nexus 1000V DHCP Snooping, DAI, and IP Source Guard

The video looks into three advanced security features on Cisco Nexus 1000V: DHCP Snooping, Dynamic ARP Inspection, and IP Source Guard. We will be testing each of the features with security audit tools, and we will be able to see how these features protect us from DHCP, ARP and source IP spoofing attacks.

RS0029 - Nexus 1000V ACL and Port Security

The video walks you through two basic security features on Cisco Nexus 1000V: Access Control List (ACL) and Port-Security. We will configure ACL on a host-facing port-profile and have any denied traffic being logged and sent to a Syslog server. We will enable Port-Security to limit the number of MAC address and test our configuration by performing MAC flooding attack.

Topic includes
  • Access Control List (ACL)
  • Port-Security
  • Errdisable Recovery
  • MAC Flooding (Macof Tool)

RS0028 - Nexus 1000V Netflow

The video demonstrates how to enable Netflow on Cisco Nexus 1000V to collect network traffic information. We will configure Netflow at vEthernet interfaces, run FTP and RDP as our test applications, and review information displayed on Netflow collector. We will also perform packet capture and analyze Netflow version 9 packets.

Topic includes
  • Netflow v9
  • Netflow Collector
  • Netflow Packet Analysis
