Who needs C9300-24UB-A for higher-scale 1G copper UPOE and Network Advantage?

C9300-24UB-A fits higher-scale 24-port 1G copper UPOE access stacks that also need Network Advantage routing and policy capabilities.

What does C9300-24UB-A add over C9300-24UB-E?

C9300-24UB-A keeps the higher-scale 24-port UPOE hardware and changes the software tier to Network Advantage.

Can C9300-24UB-A stack with 24UXB higher-scale switches?

Yes. C9300-24UB-A can be planned with higher-scale peers, but the design remains 1G UPOE on this member and mGig only on 24UXB members.

Can C9300-24UB-A stack with C9300-24U-A?

No. C9300-24UB-A is a higher-scale SKU and needs higher-scale stack peers, not standard C9300-24U-A stack members.

Does C9300-24UB-A provide 10G/mGig access ports?

No. C9300-24UB-A is a higher-scale 1G copper UPOE member. Use 24UXB when each access port needs 10G/mGig copper speed.

When does C9300-24UB-A fit routed access?

C9300-24UB-A fits routed access when higher-scale 1G UPOE hardware and Network Advantage features are both required.

When is C9300-24UB-A the wrong SKU?

C9300-24UB-A is wrong for standard C9300 stacks, 90W UPOE+ endpoints, fiber downlinks, or mGig access designs.

What Network Advantage higher-scale details matter for C9300-24UB-A?

C9300-24UB-A planning depends on higher-scale stack rules, Network Advantage scope, UPOE device wattage, StackPower, modular uplinks, and power redundancy.

C9300-24UB-A Description

C9300-24UB-A is a Cisco Catalyst 9300 higher-scale stackable access switch for campus access and aggregation deployments that need 24 Gigabit UPOE copper ports with modular uplink flexibility. Cisco positions this Network Advantage model with a default 1100W AC power supply that delivers 830W of PoE, StackWise-480 for higher-scale stacking, StackPower support, and the 32 MB packet buffer used on higher-scale Gigabit Ethernet Catalyst 9300 variants.

Key Features

Higher-scale 24-port UPOE identity

The `C9300-24UB` hardware profile marks this as a 24-port 1G Cisco UPOE Catalyst 9300 switch in the higher-scale group, not the standard C9300-24U order line.

Network Advantage suffix

The `-A` suffix ties the hardware to Network Advantage, while the same higher-scale 24-port UPOE hardware is also listed as C9300-24UB-E with Network Essentials.

32-MB buffer for Gigabit Ethernet

Cisco lists the higher-scale Gigabit Ethernet models with a 32-MB packet buffer, a key distinction from standard 24-port and 48-port Gigabit Ethernet C9300 models.

Higher routing and policy scale

The higher-scale Catalyst 9300 column lists 64,000 MAC addresses, 112,000 IPv4 routes, 56,000 IPv6 routing entries, 18,000 QoS entries, and 18,000 ACL scale entries.

Higher-scale stacking boundary

Cisco states that C9300-24UB, C9300-24UXB, and C9300-48UB higher-scale SKUs need to be stacked with other higher-scale models.

Modular uplink order control

Cisco ordering defaults C9300 modular-uplink SKUs to C9300-NM-8X, while still allowing another C9300-NM choice or a no-network-module selection.

Application Scenarios

Higher-scale 1G UPOE access stack

C9300-24UB-A fits a Catalyst 9300 access stack that needs 24 1G UPOE ports plus the higher-scale buffer and table profile of the UB hardware family.

Advantage licensed campus refresh

The SKU suits a Network Advantage campus standard where the BOM must avoid the C9300-24UB-E Essentials line but still stay with the 24-port 1G UPOE higher-scale hardware.

Controlled higher-scale stack expansion

Use this model only where the stack plan is based on higher-scale Catalyst 9300 members, because Cisco separates C9300-24UB, C9300-24UXB, and C9300-48UB from mixed standard C9300 stacking.

In a C9300-24UB-A vs C9300-24UB-E comparison, the higher-scale 24-port UPOE hardware, 32-MB buffer, 64,000 MAC address scale, 830W PoE budget, and StackWise-480 group match; the confirmed difference is Network Advantage versus Network Essentials.
The C9300-24UB-A difference from C9300-24U-A is the scale profile: C9300-24UB-A is in the higher-scale group with a 32-MB buffer, 64,000 MAC addresses, and 112,000 IPv4 routes, while C9300-24U-A is the standard 24-port UPOE model.
For C9300-24UB-A vs C9300-24UXB-A, the comparison is 1G UPOE access versus 10G/mGig UPOE access; the C9300-24UXB model also has the 64-MB packet buffer and higher listed switching and forwarding figures.
In a C9300-24UB-A vs C9300-48UB-A comparison, the which model to choose question turns on access density because both are higher-scale 1G UPOE Network Advantage models, but the C9300-48UB SKU doubles the port count and changes the listed PoE budget and performance figures.

Selection Guide

1. Match it to higher-scale 1G UPOE access

Choose C9300-24UB-A when the BOM needs 24 1G Cisco UPOE access ports and the higher-scale Catalyst 9300 buffer, MAC, routing, QoS, and ACL profile.

2. Keep the license tier explicit

Select C9300-24UB-E instead only when the same higher-scale 24-port UPOE hardware should be ordered with Network Essentials rather than Network Advantage.

3. Do not substitute standard C9300-24U hardware blindly

Use C9300-24U-A only when the standard Catalyst 9300 scale profile is acceptable, because it does not match the higher-scale C9300-24UB buffer and table values.

4. Separate mGig and 48-port requirements

Specify C9300-24UXB-A for higher-scale 10G/mGig UPOE downlinks or C9300-48UB-A for 48 higher-scale 1G UPOE ports instead of forcing those requirements into C9300-24UB-A.

PoE Power Planning

Planning Item	Cisco Confirmed Value	Order Impact
Default PoE budget	C9300-24UB is listed with 830W available PoE and PWR-C1-1100WAC-P as the default supply	Size the powered endpoint plan to the 830W default budget unless the power design adds a second supply
Secondary supply selection	Cisco ordering selects a secondary power supply by default unless the no-secondary-supply option is chosen	Decide whether the quote should keep redundant power or remove the secondary supply from the configuration
UPOE access profile	C9300-24UB is a 24-port 10/100/1000 UPOE model	Prevent replacement with data-only, PoE+, UPOE+, or mGig order lines unless the access-port requirement changes
StackPower	C9300-24UB supports StackPower	Add StackPower cables only when the site design requires shared power across compatible Catalyst 9300 stack members

Ordering Checklist

Check Item	What to Confirm	Why It Matters
Exact SKU	C9300-24UB-A	Confirms the order is the higher-scale 24-port 1G UPOE Catalyst 9300 switch with Network Advantage
Higher-scale stack family	Stack members limited to other higher-scale C9300 models	Prevents mixing C9300-24UB with standard C9300 members in an unsupported stack plan
Advantage subscription term	Cisco Catalyst or Cisco DNA Advantage 24-port 3-year, 5-year, or 7-year subscription	Keeps the software line aligned with the 24-port Network Advantage hardware SKU
Power plan	PWR-C1-1100WAC-P default supply, 830W PoE budget, and any secondary supply requirement	Keeps UPOE endpoint power planning tied to Cisco-confirmed power values
