System default behavior

The system default behavior on the Cisco Catalyst 1000 Series is very much the same as that of the Cisco Catalyst 2960-L and 2960-Plus Series, since it runs the same base code. For example, interfaces default to the Layer 2 switch-port mode and IP routing is disabled. However, there are also some differences:

      Bluetooth over-the-air-access: The Cisco Catalyst 1000 Series supports an external Bluetooth dongle that plugs into the USB port on the switch and allows a Bluetooth-based RF connection with external laptops and tablets. Laptops and tablets can access the switch CLI using a Telnet or Secure Shell (SSH) client over Bluetooth. The GUI can be accessed over Bluetooth with a browser. This feature is available on the Cisco Catalyst 1000 and 2960-L Series; it is not available on the 2960-Plus Series.

      On-box WebUI: The Cisco Catalyst 1000 Series supports an on-box WebUI via Cisco Configuration Professional. Cisco Configuration Professional provides a user interface for day-zero provisioning, which enables easy onboarding of the switch. It also has an intuitive dashboard for configuring, monitoring, and troubleshooting the switch. This feature is available on the Cisco Catalyst 1000 and 2960-L Series; it is not available on the 2960-Plus Series.

      External power supply and energy management: The Cisco Catalyst 1000 Series provides support for an external power supply on selected SKUs, compared to built-in power supplies on the 2960-L and 2960-Plus SKUs. It also supports 802.3az Energy Efficient Ethernet (EEE), which enables ports to dynamically sense idle periods between traffic bursts and quickly switch the interfaces into a low-power idle mode, reducing power consumption. EEE is supported on the Cisco Catalyst 1000 and 2960-L Series; it is not available on the 2960-Plus Series.

Table 3 compares the power capabilities of the Cisco Catalyst 1000 Series with those of the 2960-L and 2960-Plus Series.

Single IP management

Single IP management is an efficient feature to manage and monitor switches of the network using a single IP address. Switches that support 1G and 10G Small Form-Factor Pluggable (SFP) and SFP+ uplink ports can be part of single IP management. You can use SFP/SFP+ ports with optical cables to connect switches placed at different locations to form a group, where the compact switches are placed in different floors or buildings. You can form half-ring or full-ring topologies based on need, and the remaining uplink ports will continue to work as network ports. This feature is supported only on Cisco Catalyst 1000 Gigabit Ethernet Series Switches.

Single IP management

Figure 2.            

Single IP management

When you convert a network port to a single IP-managed port, it continues to work as a network port, without any impact on the current running configuration, until the next reload of the device. All current configurations on that particular network port are lost after the reload. When you convert a single IP-managed port back to a network port, it comes up as a network port with the default configuration, after a reload.

Up to eight members can join a group through single IP-managed ports. A group always has one master, and the other devices act as members. You can have a group with one master and one member, the maximum number in the group being eight. The configuration file for all the switches connected in a group is maintained by the master.

The following shows the port status during and after conversion to a single IP managed port.

This feature is supported only on Cisco Catalyst 1000 Series Switches.

Flexible PoE options

The Cisco Catalyst 1000 Series Switches offer flexible PoE options. The PoE power allocation in the switches is dynamic, and power mapping scales up to a maximum of 740W of PoE+ power. Intelligent power management allows flexible power allocation across all ports.

With Perpetual PoE+, the PoE or PoE+ power is maintained during a switch reload. This is important for critical endpoints such as medical devices and for IoT endpoints such as PoE-powered lights, so that there is no disruption during a switch reboot.

Software features

For a full list of features supported on the Cisco Catalyst 1000 Series, use the Cisco Feature Navigator on Cisco.com. For customers familiar with the Cisco Catalyst 2960-L and 2960-Plus Series, the following are a few differences between these switches and the 1000 Series:

Quality of Service (QOS)

Cisco Catalyst 1000 Series Switches offer intelligent traffic management that keeps traffic flowing smoothly. Flexible mechanisms for marking, classifying, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed.

Traffic management features include up to eight egress logical queues per port and strict priority queuing so that the highest-priority packets are serviced ahead of all other traffic, Shaped Round Robin (SRR) scheduling, and Weighted Tail Drop (WTD) congestion avoidance.

Table 5 compares the QoS features among the platforms.

Sampled Flow (sFlow)

Cisco Catalyst 1000 Series Switches support sFlow, which allows you to monitor real-time traffic in data networks. It uses the sampling mechanism in the sFlow agent on switches to monitor traffic and to forward the sample data to the central data collector. The sFlow agent periodically samples or polls the interface counters that are associated with a data source of the sampled packets. The data source can be an Ethernet interface or a range of Ethernet interfaces.

sFlow configuration

Figure 3.            

sFlow configuration

When you enable sFlow sampling, based on the sampling rate and the hardware internal random number, the ingress packets and egress packets are sent to the CPU as an sFlow-sampled packet. The sFlow agent processes the sampled packets and sends an sFlow datagram to the sFlow analyzer. In addition to the original sampled packet, an sFlow datagram includes information about the ingress port, the egress port, and the original packet length. An sFlow datagram can have multiple sFlow samples.

Table 6 describes the sFlow scale and performance in the Cisco Catalyst 1000 Series.

Private VLANs

The Cisco Catalyst 1000 Series is Hardware ready for PVLAN. Software support can be added in future. Private VLan also known as port isolation help to partition the Layer 2 broadcast domain of a VLAN into subdomains, allowing you to isolate the ports on the switch from each other. A subdomain consists of a primary VLAN and one or more secondary VLANs. All VLANs in a private VLAN domain share the same primary VLAN.

Types of ports in a private VLAN:

Isolated: Communicates with only promiscuous ports

Promiscuous: Communicates with all other ports

Community: Communicates with the other members of the community and all promiscuous ports

A private VLAN

A private VLAN

In the configuration in Figure 4, the DNS, web, and Simple Mail Transfer Protocol (SMTP) servers are in same subnet, wherein the DNS servers can communicate with each other and the router. However, the web and SMTP servers can communicate only with the router.

This feature is exclusive to Cisco Catalyst 1000 Series Switches.

Conclusion

The Cisco Catalyst 1000 Series is Cisco’s latest addition to the fixed enterprise switching Layer 2 platforms designed for small businesses and branch offices. It is the new generation of the small business platforms, with many additional capabilities, and is well suited for enterprises looking to migrate from their existing Cisco Catalyst 2960-L or 2960-Plus Series deployments.
