Figure 1.               

C-SM-16P4M2X – 22-port single wide (top) and C-SM-40P8M2X – 50-port double wide (bottom)

All Gigabit Ethernet ports support auto-negotiating 10G, 100G, and 1000 Mbps. Depending on the model, up to 8 ports of 2.5G Multigigabit support helps provide uplink connectivity to access points, uplink expansions, and cellular gateways for external Cat 18 LTE and 5G connections. Up to two 10G SFP+ based fiber ports provide for server connectivity or for high-speed aggregated connection to high-speed switches.

Both modules offer two SFP+ uplink ports, supporting both single-mode and multimode fiber. Each SFP+ port can be independently configured with a 1G SFP or a 10G SFP+ interface. The two fiber ports can be aggregated to provide a fault-tolerant Layer 2 port channel.

Ports with similar speed support aggregation leading to a port channel. Both Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) configuration is supported on the module in addition to automatic port channel support. Up to 4 ports of 1G or 2.5G can be aggregated to form a single EtherChannel. Ports with unlike speeds may not be aggregated to form a port channel.

Power over Ethernet (PoE) support

PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and wireless LAN deployments, thereby providing a lower TCO for deployments that incorporate these devices or any IEEE 802.3af-compliant end device in general. The power requirements of endpoints vary based on their application, complexity, and function. For instance, basic IP phones might draw approximately 6W of power, whereas contemporary LED lighting fixtures can draw up to 50W for routine operation.

The Cisco Catalyst 8000 SM-Based Switching Modules can support PoE, PoE+, and UPOE on any of the RJ-45 copper ports (16x 1G + 4x Multigigabit or 40x 1G + 8x Multigigabit). All 20 or 48 copper ports support PoE at 15.4W and PoE+ up to 30W. The same ports support standardized 802.3af (15.4W) and 802.3at (25.5W). Up to 8 copper Ethernet Interfaces provide UPOE (60W) support per module.

The table below gives information about total PoE power output. Depending on the platform model, the available PoE power ranges from 250W to 1000W. The Catalyst 8000 Edge Platforms Family supports multiple PoE powering modes:

     Normal mode: Dual PoE power supplies in active/standby redundant mode.

     Boost mode: Two PoE power supplies in active/active mode, where both are actively supplying PoE power. Redundancy is not supported in PoE Boost mode.

Security feature support on Cisco Catalyst 8000 SM-Based Switching Modules

The Cisco Catalyst 8000 SM-Based Switching Modules support the following security features.

Support for 802.1X:

IEEE 802.1X port-based authentication is configured on a device to prevent unauthorized devices (supplicants) from gaining access to the network. When the switch module is installed on the router, the unit can combine the function of a router and a switch, depending on the configuration and chosen options. The Cisco Catalyst 8000 SM-Based Switching Modules support 802.1X configuration on all copper ports. The same ports support multidomain authentication, guest VLAN, and MAC Authentication Bypass (MAB).

Support for MACsec:

MACsec is the IEEE 802.1AE standard for authenticating and encrypting packets between two MACsec-capable devices. The Cisco Catalyst 8000 SM-Based Switching Modules support 128-bit (gcm-aes-128) LAN MACsec on the copper ports. In addition to MACsec, the ports support 802.1AE encryption MACsec Key

Agreement (MKA) on downlink ports for encryption between the switch and host device. The MKA Protocol provides the required session keys and manages the required encryption keys.

Port security:

Port security is used to restrict input to an interface by limiting and identifying the MAC addresses of the stations allowed to access the port. When specific MAC addresses are assigned to a secure port, the port does not forward packets with source addresses outside the group of defined addresses. If the number of secure MAC addresses is limited to a single secure MAC address, the workstation attached to that port is assured the full bandwidth of the port.

Table 5.           Security features

Feature

Benefits

IEEE 802.1X

  IEEE 802.1X allows dynamic, port-based security, providing user authentication.
  IEEE 802.1X with voice VLAN permits an IP phone to access the voice VLAN regardless of the authorized or unauthorized state of the port.
  IEEE 802.1X and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client.
  IEEE 802.1X with an Access Control List (ACL) assignment allows for specific identity-based security policies regardless of where the user is connected.
  IEEE 802.1X with guest VLAN allows guests without 802.1X clients to have limited network access on the guest VLAN.

MACsec

  Exceptional security with integrated hardware support for MACsec is defined in IEEE 802.1AE. MACsec provides MAC layer encryption over wired networks using out-of-band methods for encryption keying.
  The MKA Protocol provides the required session keys and manages the keys required for encryption when configured. MKA and MACsec are implemented following successful authentication using the 802.1X Extensible Authentication Protocol (EAP) framework.
  Both the user and downlink ports (links between the switch and endpoint devices such as a PC or IP phone), as well as the network and uplink ports, can be secured using MACsec.
  With MACsec you can encrypt switch-to-switch links such as access to distribution or encrypt dark fiber links within a building or between buildings.

Multidomain authentication

  Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on the appropriate voice and data VLAN.

MAC Authentication Bypass (MAB)

  MAB for voice allows third-party IP phones without an 802.1X supplicant to get authenticated using the MAC address.

Switched Port Analyzer (SPAN and RSPAN)

  Bidirectional data support on the SPAN port allows the any intrusion detection system to take action when an intruder is detected.

Centralized authentication

  TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.

MAC address notification

  MAC address notification allows administrators to be notified of users added to or removed from the network.

Port security

  Port security secures the access to an access or trunk port based on MAC address.

Customer need

How addressed by the switching modules

Scalability with high-performance LAN traffic

  Layer 2 traffic is switched locally on board the module.

High-speed LAN connections

  Maintain switch-to-access point reach at Multigigabit (2.5G) speeds: Support for access extensions and uplinks.
  10G fiber connections provide for high-speed server or LAN backbone connections.

Layer 2 security for protecting the integrity and confidentiality of all traffic on the LAN

  1G Ethernet copper ports support LAN MACsec to LAN endpoints.
  2.5G (Multigigabit) LAN MACsec protects traffic to access points, cellular gateways, or high-speed servers.

Applying Layer 3 services to switched traffic

  Since the switch module is Layer 2 capable only, the host router’s Switch Virtual Interface (SVI) is used for applying Layer 3 services to traffic traversing the switch.
  An SVI service provides a limited set of Layer 3 features and is fully software operated. As such, throughput when using the SVI will depend on the types and combination of services applied to traffic.

Scaling network infrastructure across multiple sites

  An integrated switch solution lowers operating costs, simplifies troubleshooting, and enables businesses to scale.

Lowering costs of operating multiple devices at the branch office

  The modules offer a lower Mean Time To Repair (MTTR). One vendor means one support center to decrease troubleshooting time and eliminate finger pointing among vendors.
  Cisco Smart Net Total Care ® support covers both 8300 Series and Cisco switch module devices.

Maximizing IT resources

  Single host router-based unified IOS software helps ensure that the IT team has to install and certify only one operating system.

Investment protection by helping ensure compatibility with future networks to deliver leading technology

  Cisco Catalyst 8000 SM-Based Switching Modules and Cisco Catalyst 9000 switches both run the same Cisco IOS XE software base, helping ensure a consistent user experience.
  Cisco Catalyst 9000 switches and Cisco Catalyst 8000 SM-Based Switching Modules both support the latest UADP 2.0 ASIC, helping ensure cross-platform support for the latest innovations.

High availability that minimizes downtime that affects business operations

  A single-box and single IOS solution simplifies remote management and improves services interoperability to help ensure the highest reliability.
  End-to-end testing for standards-based and innovative Cisco proprietary features provides superior services interoperability and excellent value.
  The modules use the redundant power supplies of the host Cisco Catalyst 8300 Series platforms.
  Fewer components (for example, power supplies and fans) means fewer failures and less downtime.

Sustainability

  The modules offer lower power consumption than previous generation of switch modules.
  Because no additional rack space or power supply is needed, there is less to rack, stack, and cool.
