Predictika · Arista data center switching quotes

An AI sales agent's switching quote, checked before it goes out

An AI sales agent prepares a quote for Arista 7050X3 and 7280R3 data center switches with optics, a CloudVision subscription and an A-Care service contract. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product and quoting rules, compares the total the quote states with the computed one, and returns every finding together with the line-item quote. This is an illustrative model built from Arista's public product information with Predictika illustrative figures for prices, support percentages, rates, lead times and discount limits; it is not Arista's internal rule set.

Illustrative figures. Prices, A-Care percentages, CloudVision rates, lead times and discount limits on this page are Predictika illustrative figures, not Arista's. Arista does not publish them here. The switch models, port types, optic names and reach, the A-Care service levels and the CloudVision license names are real Arista names taken from public sources.

Scope: quotes for Arista data center switching: the DCS-7050X3 and DCS-7280R3 families with optics, CloudVision and A-Care. See everything this validator covers

This validator models one product line: Arista data center switching, specifically the DCS-7050SX3 and 7050CX3 and the DCS-7280SR3, 7280SR3M and 7280CR3 switches. It handles any quote involving these switches, their optics, CloudVision subscriptions and A-Care contracts, not only the scenarios shown on this page. It does not cover Arista campus switching, routing, or software-only products.

  • Covered: switches — six models in leaf, spine, DCI and edge roles, with the SFP, QSFP100 and OSFP400 port counts of each, deep-buffer and MACsec capability, and lead times.
  • Covered: optics — SFP 10G and 25G, QSFP 100G and OSFP 400G optics, matched to the port type, the number of ports and the reach needed for the access links and the uplinks.
  • Covered: software and support — CloudVision and CloudVision Lite subscriptions, A-Care Next Business Day and 4-Hour Replacement service levels, terms of 1, 3 or 5 years under the illustrative policy (4-Hour Replacement not allowed at remote sites in that policy), and the waivers for no support and for large fabrics without CloudVision.
  • Covered: commercial terms and the quote — spine redundancy, lead time against the date needed, discount authority (rep limit and the maximum), a cap on the CloudVision discount, the line-item quote, and the total the agent states.
  • Not covered — other Arista families (7060X, 7800R, campus and wireless), mixed-model fabrics, cabling and breakout optics, power and rack planning, and real Arista prices, discount schedules or order-routing rules. Other areas can be added.
  • Labeled as Predictika illustrative figures, not Arista's — all prices, A-Care percentages, CloudVision rates, lead times, the 30 and 45 percent discount levels, the 20 percent CloudVision discount cap, the 1, 3 or 5 year term rule, the remote-site rule, the deep-buffer rule for DCI and edge roles, the 8-switch management waiver and the support waiver.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Optic checks that combine form factor, port type, port count and reachOnly with workarounds
Each optic has to be checked against the switch model it is placed in and against the length of the link it serves. Rules-based CPQ turns this into optic-by-switch compatibility rules and a distance rule per optic, which have to be extended for every new optic or switch.		Form factor, matching ports, port count and reach come from catalog attributes and are checked together; a QSFP optic in SFP ports and an SR optic over a 150 m uplink both come back on one call.
Hardware that the role requires, not a single SKU exclusionOnly with care
A DCI or edge role needs a deep-buffer switch, and MACsec needs the M model. These are role-to-capability requirements. They can be written as rules per role and model, but each new model or role adds rules that someone has to remember.		Role, buffer depth and MACsec capability are checked together; both problems on the 7050SX3 DCI order come back in the same answer.
Discount authority with separate caps and waiversOnly with care
A rep limit, a maximum above it, a separate cap on the CloudVision discount, and waivers for no support or a large fabric without CloudVision are layered thresholds. Approval chains handle one threshold well; several together need care to keep in step.		Rep limit, maximum, CloudVision cap and both waivers are checked on every call; 50 percent blocks and 38 percent goes to approval.
A stated total that does not match the computed priceOnly with workarounds
A validation rule can compare a stated total with a calculated field, but only if the stated total is a field on the quote, which it rarely is.		The stated total travels with the quote and is compared with the computed one on every call.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
110 switches without CloudVision; the illustrative policy requires a management waiver for fabrics of 8 or more.
210 uplink optics per switch exceed the 8 matching uplink ports on DCS-7280SR3-48YC8.
350 access optics per switch exceed the 48 SFP ports on DCS-7280SR3-48YC8.
4A CloudVision discount of 25 percent is above the 20 percent cap in the illustrative policy.
5A discount of 38 percent is above the 30 percent a rep may give alone under the illustrative policy.
6A discount of 50 percent is above the 45 percent maximum in the illustrative policy.
7A spine layer needs at least 2 switches for redundancy.
8Access optic QSFP-100G-SR4 is not an SFP module and cannot go in the SFP ports of DCS-7050SX3-48YC8.
9MACsec is required but DCS-7050SX3-48YC8 has no MACsec ports; use the 7280SR3M.
10Optic QSFP-100G-SR4 reaches 100 m but the uplinks run 150 m.
11Optic SFP-25G-SR reaches 100 m but the access links run 101 m.
12Stated total does not match: the agent stated $271,500.00; the validator computes $259,000.00.
13The illustrative lead time for DCS-7280SR3M-48YC8 is about 12 weeks; the customer needs it in 11 weeks.
14The illustrative policy allows CloudVision and A-Care terms of 1, 3 or 5 years; 2 years is outside it.
15The illustrative policy does not allow A-Care 4-Hour replacement at remote sites.
16The quote has no A-Care support contract; the illustrative policy requires a support waiver.
17Under the illustrative policy the DCI role needs a deep-buffer 7280R3 switch; DCS-7050SX3-48YC8 is shallow-buffer.
18Uplink optic OSFP-400G-DR4 has no matching uplink ports on DCS-7050SX3-48YC8.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for Arista 7050X3 and 7280R3 data center switches with optics, a CloudVision subscription and an A-Care service contract. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product and quoting rules, compares the total the quote states with the computed one, and returns every finding together with the line-item quote. This is an illustrative model built from Arista's public product information with Predictika illustrative figures for prices, support percentages, rates, lead times and discount limits; it is not Arista's internal rule set.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 8 DCS-7050SX3-48YC8 leaf switches for Northgate Analytics, each. CloudVision Lite and A-Care Next Business Day for 3 years, a metro site, delivery within 12 weeks and a 25 percent discount. The rest of the request is on screen. The quote states a total of $387,840.00.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. Access optic QSFP-100G-SR4 is not an SFP module and cannot go in the SFP ports of DCS-7050SX3-48YC8. Optic QSFP-100G-SR4 reaches 100 m but the uplinks run 150 m.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for optic checks that combine form factor, port type, port count and reach, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the access optic to SFP-25G-SR, the uplink optic to QSFP-100G-CWDM4 and the stated total to $307,200.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The validator also returns the line-item quote. It starts with DCS-7050SX3-48YC8 and SFP-25G-SR; the other four lines are on screen.
    13. 
      
  13. Both earlier findings are cleared, and the validator's total, $307,200.00, matches the quote.
    14. 
      
  14. Two problems caught in one call, fixed in one pass, and a clean $307,200 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    15.
