C9300-48T-A Description

The C9300-48T-A is a Cisco Catalyst 9300 Series stackable access switch for data-only wiring closets that connect 48 copper endpoints at Gigabit speed. The switch has 48 10/100/1000 copper ports, a modular uplink slot, 256 Gbps of switching capacity and a 350W AC supply with no PoE budget. The -A suffix carries Network Advantage, which adds BGP, EIGRP, VRF, VXLAN, TrustSec and MACsec-256 to the Layer 2 and routed-access set of Network Essentials.

Key Features

Open Modular Uplink Slot

The slot takes C9300-NM-8X for eight 10G/1G SFP+ ports, or 1G, 25G and 40G modules. The aggregation speed is chosen at deployment and can change later by swapping the module.

Unrestricted Routing Scale

Network Advantage lifts the 1,000-route OSPF cap of Network Essentials and adds BGP, EIGRP, IS-IS and PIM-BIDIR. The closet can then act as a routed edge instead of a pure Layer 2 hop.

VRF, VXLAN And TrustSec Segmentation

VRF, VXLAN, LISP and Cisco TrustSec split tenants or departments across one set of 48 ports. These are Network Advantage features that Network Essentials does not carry.

Model-Driven Automation Interfaces

NETCONF, RESTCONF, gRPC and YANG models let a controller or script configure the switch. Zero-touch provisioning is also part of the Network Advantage set.

MACsec-256 Link Encryption

Network Advantage raises link encryption from the MACsec-128 of Network Essentials to MACsec-256. Switch-to-switch and switch-to-host links can then be encrypted at the stronger key length.

StackWise-480 With StackPower

Up to eight units stack at 480 Gbps, and StackPower shares power across the stack. Every member must run Network Advantage.

Application Scenarios

Routed Access Building

In a campus building that routes at the access layer, the switch runs BGP, EIGRP or OSPF without a route cap toward the distribution layer.

Segmented Desktop Floor

On an office floor where several departments share one closet, the switch keeps their desktop and workstation traffic apart with VRF or VXLAN segmentation.

Automated Campus Rollout

Across a campus with many closets, the switch accepts NETCONF, RESTCONF and YANG-driven configuration, so one controller can provision all of them.

Network Advantage

C9300-48T-A and C9300-48T-E are the same 48-port data-only hardware on a 350W supply, and the license is the only difference: C9300-48T-A carries Network Advantage, so it can be replaced by C9300-48T-E only where BGP, VRF, VXLAN and Cisco TrustSec are not needed, and Cisco lists no downgrade PID. Closets that need only 24 data ports can use C9300-24T-A, which has 208 Gbps of switching capacity against 256 Gbps. Any port that must power phones or access points requires C9300-48P-A, which provides 437W of PoE on a 715W supply, because C9300-48T-A has no PoE.

Ordering Checklist

  • Software subscription: Order an Advantage term for the 48-port copper group, such as C9300-DNA-A-48-5Y or C9300-DNX-A-48-5Y (3, 5 or 7 years). Cisco DNA Advantage with a 5-year term is the configurator default, and the subscription must match the switch tier on new orders.
  • Uplink module: Keep the default C9300-NM-8X, change it to another Catalyst 9300 network module, or select C9300-NM-NONE. The configurator fills the modular uplink slot, so the default adds a module to the order.
  • Second power supply: A second supply matching the primary is selected by default and C9300-SPS-NONE removes it. Leaving the default adds a second supply to the order; removing it leaves the switch on a single supply.
  • Stack cables: A 50 cm StackWise cable and a 30 cm StackPower cable are selected by default; C9300-STACK-NONE and C9300-SPWR-NONE remove them. A stack across racks needs longer cables ordered separately, and a standalone switch needs neither default.
  • Power cords: Select the cord type for the destination country. The configurator defaults to North America cords and ships two.

Questions & Answers

  • Can C9300-48T-A be stacked?

    Yes. C9300-48T-A stacks over StackWise-480 with up to eight units, and every member must run Network Advantage. StackPower shares power across the stack. A stack across racks needs longer StackWise cables ordered separately.
  • Does C9300-48T-A support BGP?

    Yes. Network Advantage on C9300-48T-A removes the 1,000-route OSPF cap and adds BGP, EIGRP, IS-IS and PIM-BIDIR. VRF, VXLAN, LISP, Cisco TrustSec and MACsec-256 are included, along with NETCONF, RESTCONF, gRPC and YANG programmability.
  • Does a C9300-DNA-A-48-5Y term for C9300-48T-A include ThousandEyes?

    Yes. The Advantage term brings the ThousandEyes Network and Application Synthetics license, PID TE-EMBEDDED-T, at no extra charge for the same term as the subscription. This applies to 3-year, 5-year and 7-year terms. D-DNAS-EXT-S-T for Cisco Spaces Extend is bundled in the same way.
  • What are the default Access SDM template limits on C9300-48T-A?

    The default Access template on C9300-48T-A allows 4094 VLANs, 32,768 unicast MAC entries and 24,576 directly connected routes. It also allows 8,192 indirect routes and 1,024 PBR ACEs. IPv6 entries take two slots each. Check the active template with the show sdm prefer command after any change.
  • Which power supplies besides PWR-C1-350WAC-P fit C9300-48T-A, and what redundancy applies?

    Catalyst 9300 chassis take 350W AC, 715W AC, 715W DC, 1100W AC and 1900W AC supplies. Each switch holds two supplies in an N+1 arrangement. All are Platinum-rated at 90% efficiency except the DC unit, which is Gold-rated. Per the Cisco datasheet, the supply PIDs end in -P for the Platinum AC models.
  • Can C9300-48T-A use the PWR-C1-1900WAC-P power supply?

    Yes. PWR-C1-1900WAC-P is listed as an available supply for modular-uplink Catalyst 9300 models and can be mixed with the other 9300 supplies. It delivers 1500W at 115V input and 1900W at 230V input. It also takes its own power cord, so order that cord with it.
  • What must sit in the uplink slot of C9300-48T-A if no network module is ordered?

    Fit a C9300-NM-BLANK filler. The switch runs only with a network module or the C9300-NM-BLANK installed, and the filler also preserves airflow through the chassis. The chassis ships with no network module by default, so select C9300-NM-NONE in the configurator only if the blank is also supplied.
  • How is the 480 Gbps StackWise-480 bandwidth of C9300-48T-A built?

    StackWise-480 uses 6 rings of 40 Gbps each, which add up to the 480 Gbps stack bandwidth. A stack holds up to 8 members. Every member must run the same license tier, so Network Essentials and Network Advantage switches cannot share a stack. Per the Catalyst 9300 datasheet, plan the ring cabling with that limit in mind.
  • How deep is C9300-48T-A with the 1100W supply installed?

    C9300-48T-A is 19.2 in deep with an 1100W secondary supply installed. With only the default supply it is 17.7 in deep. You must allow for the longest figure when you install the switch in a shallow rack, per the Catalyst 9300 datasheet.
  • How many C9300-48T-A switches can share power in a StackPower ring?

    Up to four C9300-48T-A switches can share power in a StackPower ring with 1+N redundancy. An XPS 2200 extends this to eight switches in a star topology. One eight-member data stack can hold two power stacks. Order CAB-SPWR-30CM or CAB-SPWR-150CM for the cabling. StackPower works only on modular-uplink Catalyst 9300 and 9300X switches.
