Inter-VLAN routing is the process of forwarding network traffic from one VLAN to another VLAN using a
router.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to
communicate with hosts in another VLAN, the traffic must be routed between them. This is known as
inter-VLAN routing. On Catalyst switches it is accomplished by creating Layer 3 interfaces (Switch virtual
interfaces (SVI)).

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Two Types of Unified Computing Servers
1. Rack Mountable servers – C Series Servers
2. Blade servers – B Series servers
3. Physical Architecture of UCS - Blade Servers
• Fabric Interconnects ( FIs )
• Core of UCS platform
• Everything connects to FIs
• FIs run the actual UCS Manager software ( XML API )
• Chassis
• Chassis contains blades , but no intelligence
• Blades contains CPU/RAM/CNAs
• IOM / FEX
• IO muxes data from FIs to blades
• CMS ( Chassis management switch )
• Carries management traffic from/to CIMC (Cisco Integrated Management
Controller ) on FI
• CMC ( Chassis Management controller )
• Monitors all sensors , voltage , controls fan speed
• Used in discovery of the chassis , blades and IOMs.
11. • FI – A connects with FI-B with a pair of cables – not for data , but only for
management purpose.
CMS CMS
• CMS are inbuilt in IOM/FEX. CMC on both the IOM/FEX are internally connected
to CMC of each and every blade.
12. • From each VIC/Emulex/CNA card ( mezzanine card ) on the blade a set of links
goes to IOM-A and other set of links goes to IOM-B. No. of Links depends upon
the card type.
13. • Uplinks from VIC to IOM are port channeled by default. The size of the port
channel depends upon the number of ports available on a particular card.
• Traffic from particular Application on VM/ESXi ( through vNIC) can select the
path towards the IOM-A or IOM-B with the concept of vPC Host Mode or MAC
Pinning ( based on source MAC address).
14. • In IOM/FEX ( 2208 XP ) there will be 8 ports facing the FI and 32 ports facing the
blades. Because we have max 8 half blades or 4 full blades in a chassis. On any
card we can have max 8 ports ( 4 towards IOM-A and 4 towards IOM-B ). So 8
blades x 4 ports on each blade = 32 Ports.
• It means that we do have oversubscription ratio of 8:32.
15. Selection of ports for traffic flow from IOM to Fabric Interconnect – Dynamic
Pinning
• If only one link exist than all the blades will send traffic towards that link shown
by red colour.
16. • If two link exist than all the odd number blades will send traffic towards link-1
shown by red colour and the even number blades will send traffic towards link-2
shown by green colour.
17. • If four link exist than the blades 1&5 will send traffic towards link-1 shown by
red colour and the blades 2&6 will send traffic towards link-2 shown by green
colour. Blades 3&7 will send traffic towards link-3 shown by blue colour and the
blades 4&8 will send traffic towards link-4 shown by yellow colour.
18. • If eight link exist than each blade will take as per the below diagram.
19. Selection of ports for traffic flow from IOM to Fabric Interconnect – Port Channel
• In case of port channel the load will be distributed using hash algorithm. No
mapping of particular port with particular blade. This is most recommended
method of deployment. Port channel can be of 2/4/8 ports.
21. Benefits Of UCS
1.Stateless computing: server does not have any MAC,WWN,NIC’s,UUID
address,Firmware and BIOS setting all abstracted from UCSM s/w running on FI.
2. Rapid Provisioning of Server: All identity installed from UCSM thus hundred of serevrs can be deploy
with in a days by creating templates.
3. Simplified troubleshooting: As stateless computing thus installing new server abstract all details of old
server from UCSM.
4.Virtualization readiness: Support all major hypervisor platform including VMware
ESXi, Microsoft hyper-V and citrix Xen Server.
5. Choice Of industry Form Factor: Both B-series and C-series server are designed using Intel Xeon CPU.
22. UCS hardware options
Fabric Interconnects
• Provides network connectivity (both LAN and SAN) and management of connected server.
• UCSM lies inside fabric interconnect can access through management interface.
• Core component of UCS Solution.
• Support all FCoE,FC and ethernet ports.
• FI are deployed in clustered pairs to provide high availability(Active-Active topology)

38. 1. No spanning-tree protocol (STP); no blocked ports.—Simplified Upstream Connectivity.
2. Admin differentiates between server and network ports.
3. Using dynamic (or static) server to uplink pinning.
4. No MAC address learning except on the server ports; no unknown unicast flooding.
5. Fabric failover (FF) for Ethernet vNICs (not available in switch mode).
End-host mode (EHM): Default mode
Fabric interconnect
52. End Host Mode Unicast Forwarding
RPF:unicast/multicast traffic is forward to server only if it arrives on correct pinned uplink port.
Deja-vu-check: Packet with source mac-address to a server received on an uplink port is dropped.
53. 1. Fabric Interconnects behave like regular ethernet switches.
2. STP configured for loop avoidance.
3. The uplinks ports are configured as forwarding or blocking as per the STP algorithm.
4. Not a default mode of operation.
Fabric Interconnect – Ethernet Switch Mode - Overview
54. Northbound of the Fabric Interconnect – Ethernet Switch
Mode - Overview
55. Designated Broadcast/Multicast Uplink Ports
• For any Broadcast/Multicast southbound traffic from N5K moving downward toward UCS Fabric Interconnects ,there
has to be a designated port on FI-A and FI-B.
• Suppose UCS FI-A chooses Po1 as its designated Broadcast/Multicast traffic receiver Port.
• Suppose UCS FI-B chooses Port 1/19 as its designated Broadcast/Multicast traffic receiver Port.
• Any Broadcast/Multicast traffic coming from N5K to UCS FI , but not on the defined as designated
Broadcast/Multicast ports will be dropped.
• Outgoing Broadcast/Multicast traffic is allowed on all the ports.
56. Blade server-1
Broadcast/Multicast Traffic
• Any incoming Broadcast/Multicast traffic is allowed only on designated Broadcast/Multicast ports only
and will be dropped on any other ports. This is to avoid loops as no STP is running .
• Outgoing Broadcast/Multicast traffic is allowed on all the ports.
Blade server-2
57. • Suppose UCS FI-B chooses Port 1/19 as its designated Broadcast/Multicast traffic receiver Port.
• vNIC2 ( having mac 00B1 ) is pinned to UCS FI-A uplink 1/17
• Any Broadcast/Multicast outgoing traffic coming from Server -1 vNIC 2 to UCS-F1-A will be blocked at all the ports on UCS FI-B except
1/19 .
• Any Broadcast/Multicast outgoing traffic coming from Server -1 vNIC 2 to UCS-F1-A and then again coming back to UCS FI-A via N5K1
to Po1 will also be dropped. This is called Deja-Vu Check (If I have seen that traffic(src-mac address) before ……drop it). This prevents
the loop.
59. Key Points
1. Server vNIC pinned to an uplink port.
2. NO STP Protocol.
3. Maintains Mac table for server only not entire data center.
4. Prevent loops by preventing Uplink-to-uplink switching.
5. Upstream VPC/VSS optional(Best practice).
6. Server-to-Server traffic on the same vlan switched locally.
60. Recommended Topology for Upstream Connectivity
Always dual-attach each fabric interconnect to two Cisco Nexus 7000 Series Switches for high availability and redundancy whether
using vPC uplinks or individual uplinks without vPC.
62. Connectivity –SAN
FI Modes of Operation -SAN
N_Port Virtualisation(NPV) Mode : Default, recommande mode
1. UCS relays FCIDs to attached devices –No domain ID to maintain locally
2. Zoning, FSPF, alias etc. are not configured on the UCS Fabrics
3. Domain Mgr., FSPF, Zone Server, Fabric Login Server, Name Server do not run on UCS Fabrics.
63.
64. SAN Fabric Interconnect FC/FCoE Mode of Operation –Switch Mode
1. UCS Fabric Interconnect behaves like an FC fabric switch.
2. Storage ports can be FC or FCoE.
3. Local Zoning OR Upstream Zoning(Upstream Zoning Provided by MDS/N5k).
4. Fabric Interconnect uses a FC Domain ID.
5. Supported FC/FCoE Direct Connect Arrays.
