DATACENTER AS AN APPLICATION™

Dataplane and protocol capabilities

Up to 256 virtual ‘wires'
Access and 802.1Q trunk ports, native VLANs, and allowed VLAN add/remove/except operations
VLAN-aware dynamic and static MAC learning, movement detection, and aging
Protected ports and primary/isolated/community private VLANs
Single common-instance rapid spanning tree with PortFast, BPDU Guard, Root Guard, and Loop Guard
Static port channels and active/passive LACP with flow hashing and flood de-duplication
IPv4 IGMP and IPv6 MLD snooping
LLDP transmit, receive, neighbor aging, topology metadata, and traffic counters
Four SPAN sessions with multiple sources, RX/TX/both, monitor-only port destinations, and direct PCAP destinations
Monitor destinations are non-forwarding by default
Storm control, sticky port security, violation policy, err-disable, and timed recovery
Per-port capture with size limits, rotation, duration, and MAC filtering
Per-port delay, jitter, loss, duplicate, reorder, corruption, and rate impairment
Controlled cable-state simulation and test-EtherType frame generation

IEEE 802.1ad / QinQ support

IVMware doesnt do this. STRATUM does.

True outer S-tag 0x88a8 and inner C-tag 0x8100
Customer-facing Q-in-Q ports that preserve the customer's VLAN
Provider trunks that switch/MAC-learn using the S-VLAN
S-tag insertion/removal without modifying the inner C-tag
Strict provider trunk behavior: bare C-tags cannot masquerade as S-tags
Existing normal 802.1Q access/trunk behavior unchanged by default
Double-tag-aware IGMP/MLD parsing
CLI/config persistence and control-API reporting
Extra frame-size allowance for the second VLAN header

! Customer/test-bay side
interface Ethernet0/1
switchport mode qinq
switchport qinq service vlan 500

! Provider/fabric-facing side

CLI capabilities

Up to eight concurrent EXEC/read-only sessions with a single exclusive configuration lock
Cisco-familiar EXEC/global/interface/interface-range/VLAN modes
Unambiguous abbreviations, `?` help, tab completion, history, cursor editing, and paging
Interface ranges and `default interface`
`do` commands from configuration mode
`| include`, `exclude`, `begin`, `section`, `count`, and `redirect`
Configuration checkpoints, history, diff, rollback, and confirmed rollback
Expanded interface, VLAN, MAC, RSTP, LACP, LLDP, multicast, PVLAN, SPAN, capture, security, and impairment views
STRATUM-specific runtime/fabric/topology validation and diagnostics
`show tech-support` suitable for console copy/paste or redirection to the workspace

STRATUM distributed execution

The switch has a dedicated STRATUM orchestration/runtime path, the same path virtual machines are deployed/executed/migrated/scaled/moved. 
On a selected STRATUM worker it:
 

• Creates the switch virtual wires and ports. 

• Creates or joins ordinary vdatacenter bridges and stable-VNI VXLANs.

• Uses STRATUM Connect (Continuum) fabric interface, address, peer flood list, and payload MTU when available.That means you can have a

• Validates arbitrary external bridge-backed network objects,  or any configured cloud bridge.

STRATUMswitch works with VMs across your on-premise datacenter, edge, and cloud systems within the STRATUM Continuum (network mesh).
