Upgrading the Switch Software
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release number. The files necessary for web management are contained in a subdirectory. The image is stored on the system board flash device (flash:).
You can use the show version privileged EXEC command to see the software version that is running on your switch.
Note Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
The software image can also be upgraded over bluetooth using the Cisco Digital Building smartphone app.
Features of the Switch
The Cisco Digital Building switch supports the LAN Lite feature set. This provides standard Layer 2 security, quality of service (QoS) features, and other features that are unique to CDB. The switch models have reduced functionality and scalability with entry level features in Layer 2, and provide no routing capability. They do not support stacking.
The feature sets are described in the following sections.
PoE+ or Cisco UPOE available on all 8 Fast Ethernet downlink ports. Each switch also contains 2 Gigabit Ethernet copper uplink ports.
Depending on the switch model, a total of either 240 W or 480 W power is available for endpoints.
Automatic device classification for various endpoints such as lights, IP phones, wireless access points, and cameras..
Deep Sleep, where the switch goes into a low standby power mode and draws only 0.5 W per port, thus enhancing power efficiency.
Constrained Application Protocol (CoAP) support, for use with constrained devices to enable Internet of Things (IoT).
Perpetual UPOE, a first in the industry, that ensures uninterrupted power for endpoints during switch upgrade, reboot, and configuration changes.
Smartphone-based management of the switch over bluetooth via mobile app.
Plenum certification, that enhances safety by restricting the burning of cables when exposed to heat or fire.
Ease of Operations
Cisco Catalyst Smart Operations is a comprehensive set of features that simplify LAN deployment, configuration, and troubleshooting. Catalyst Smart Operations enable zero touch installation and replacement of switches and fast upgrade, as well as ease of troubleshooting with reduced operational cost. Catalyst Smart Operations is a set of features that includes Smart Install, Auto Smartports, Smart Configuration, and Smart Troubleshooting to enhance operational excellence:
– Cisco Smart Install is a transparent plug-and-play technology that can configure the Cisco IOS software image and switch configuration without user intervention. Smart Install uses dynamic IP address allocation and the assistance of other switches to facilitate installation.
– Cisco Auto Smartports provide automatic configuration as devices connect to the switch port, allowing auto detection and plug and play of the device onto the network.
– Cisco Smart Configuration provides a single point of management for a group of switches and in addition adds the ability to archive and back up configuration files to a file server or switch allowing seamless zero touch switch replacement.
– Cisco Smart Troubleshooting is an extensive array of debug diagnostic commands and system health checks within the switch, including Generic Online Diagnostics (GOLD) and Onboard Failure Logging (OBFL).
– Auto Configuration determines the level of network access provided to an endpoint based on the type of the endpoint device.
Cisco Prime Infrastructure is a set of tools that enables you to automate much of the management of your Cisco network.
Interface templates provide a mechanism to configure multiple commands at the same time and associate it with a target (such as an interface). An interface template is a container of configurations or policies that can be applied to specific ports.
The Cisco Digital Building series switches provide a range of security features to limit access to the network and mitigate threats.
Port security secures the access to an access or trunk port based on MAC address. It limits the number of learned MAC addresses to deny MAC address flooding.
DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers.
Dynamic ARP inspection (DAI) to prevent malicious attacks on the switch by not relaying invalid ARP requests and responses to other ports in the same VLAN.
Flexible authentication via 802.1x and MAC Authentication Bypass using a single, consistent configuration.
Open mode that creates a user friendly environment for 802.1X operations.
Comprehensive RADIUS Change of Authorization capability for asynchronous policy management.
ACLs define security policies on interfaces for control-plane and data-plane traffic. IPv6 ACLs can be applied to filter IPv6 traffic. Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.
Secure Shell (SSH) Protocol and Simple Network Management Protocol Version 3.
(SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
Bidirectional data support on the Switched Port Analyzer (SPAN) port allows Cisco Intrusion Detection.
TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.
MAC address notification allows administrators to be notified of users added to or removed from the network.
Multilevel security on console access prevents unauthorized users from altering the switch configuration.
Bridge protocol data unit (BPDU) Guard shuts down Spanning Tree PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
IGMP filtering provides multicast authentication by filtering out non-subscribers and limits the number of concurrent multicast streams available per port.
802.1x monitor mode allows companies to enable authentication across the wired infrastructure in an audit mode without affecting wired users or devices. It helps IT administrators smoothly manage 802.1x transitions by allowing access and logging system messages when a device requires reconfiguration or is missing an 802.1x supplicant.
Deployment and Control Features
Dynamic Host Configuration Protocol (DHCP) Auto-configuration of multiple switches through a boot server eases switch deployment.
Auto-negotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups and Gigabit groups.
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad.
Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect wiring. Also, port faults can be detected and disabled on the interfaces.
Internet Group Management Protocol (IGMP) v1, v2, v3 Snooping for IPv4. MLD v1 and v2 Snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors.
Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting.
The Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.
Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination.
Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location.
Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.
Storm control for unicast, broadcast and multicast traffic to prevent disruption in the network due to packet flooding on the LAN.
Switch-port auto-recovery (error-disable) automatically attempts to reactivate a link that is disabled because of a network error.
Auto-LAG and etherchannel min-link support.
Quality of Service
Up to 4 egress queues per port and strict priority queuing, and finer flow segregation using 2 threshold markers for non-strict-priority queues.
Strict priority queuing to ensure that the highest-priority packets are serviced ahead of all other traffic.
Limitations and Restrictions
The switch does not support routing protocols.
The switch has 180 free TCAM entries, which are allocated between MAC ACE, IPv4 ACE and IPv6 ACE entries.
Extension header match options for IPv6 PACLs are not supported on the switch. Also, PACLs not supported in the out direction.
The switch does not support jumbo frames.
IPv4 access-list supports only the eq layer-4 operator.
