Transcript of VDC by NETWORKERS HOME
Virtual Device ContextsVDCs used to virtualize physical hardware of Nexus 7000(As
SDRs in IOS XR or Contexts in ASA)
VDCs also virtualize control plane protocols of Nexus 7000
Separate control plane per VDC
OSPF 1 in VDC 1 is not OSPF 1 in VDC 2
Multiple logical roles per physical chassis
E.g. Core, Aggregation/Distribution & access on same box
Multi-Tenancy
Some features can’t co-exist in same VDC
OTV and VLAN interfaces (SVIs)
F2 cards and M1/F1
No Of VDCs 4 VDCs per chassis with SUP 1
4+1 VDCs per chassis with SUP 2
8+1 VDCs per chassis with SUP 2E*
No internal cross VDC communication
Physical cable can be used to connect VDCs
Default VDCDefault VDC “1” always exists and cannot be removed
& used to create and manage other VDCs
Controls VDC port allocations & VDC resource allocations
Number of VLANs, VRFs, Routing table memory
All ports allocated to default VDC at initialization
The VDCs that are used by the Cisco Nexus 7000 Series switches separate data plane, control plane, and management plane functions.
Default VDC tasksSome tasks can only be performed in the default VDC
• VDC creation/deletion/suspend
• Resource allocation – interfaces, memory
• NX-OS Upgrade across all VDCs
• ISSU Upgrade
• Feature-set installation for Nexus 2000
• Fabric Path and FCoE
• Port Channel load balancing
• ACL Capture feature enable
• System-Wide QoS
Admin VDC Supported on supervisor module Sup2/2E and the new
Cisco NX-OS version 6.1
Licenses are installed and activated in the Admin VDC
Creation and deleting of VDC is done in Admin VDC
Cannot perform any traffic forwarding
Layer 2 and Layer 3 functionality is disabled
