Introduction The Catalyst switches are the next generation of enterprise class stackable access layer switches that provide full convergence between wired and wireless networks on a single platform.
By default, auto-LAG is disabled globally and is enabled on all port interfaces. The auto-LAG applies to a switch only when it is enabled globally. These make use of single strand of SMF.
The deployment of BiDi optical transceivers instantly doubles the bandwidth capacity of the existing optical fiber infrastructure. Power Supplies for the Stacking Switch—The switch has two power supplies per system, allowing the power load to be split between them.
Systems with fewer powered devices might require only one power supply. In this case, the additional power supply can provide one-to-one redundancy for the active supply. Enhancement to port security configuration—Specify a MAC address that is forbidden by port security on all interfaces. Increased scale on Catalyst Switches to support up to access points. Previously, support was up to 50 access points.
The switch supports New multi-Gigabit stackable switch model that support up to 36 ports at 1G and 12 ports at M, 1G, 2. In this phase, features such as de-congestion of incoming mDNS traffic, redistribution of service withdrawal messages, a filter criterion for learning services available on a specific interface, and the periodic browsing of services on specific interfaces are introduced.
This feature is enabled by default and is available if AVC is enabled. AN Infra—Autonomic networking makes network devices intelligent by introducing self-management concepts that simplify network management for the network operator. However, if voice VLAN and Network Modules Table 3 lists the three optional uplink network modules with 1-Gigabit and Gigabit slots.
Optics Modules Catalyst switches support a wide range of optics. Compatibility Matrix Table 8 lists the software compatibility matrix. Table 8 Software Compatibility Matrix Catalyst Cisco IOS Release. We recommend 1 GHz. Table 11 Software Images Image. Step 3 Click a switch model. The license supports up to VLANs. IP Services feature set—Provides a richer set of enterprise-class intelligent services and full IPv6 support. Interoperability with Other Client Devices This section describes the interoperability of this version of the switch software release with other client devices.
Important Notes A switch stack containing a mix of Catalyst and Catalyst switches is not supported. With Cisco Prime Infrastructure 2. Sometimes a delay is seen in the handling of ICMP reply packets when the packet timer is set to milliseconds if the value is under 1 second. This is an expected behavior. Instead, use the new radius server hostname command. On WS-C switches, if the cable plugged into port 1 has a long cable boot, the boot may stay in contact with the mode button and cause the switch to reload and reset the configuration.
To workaround this issue, use the no setup express command to disable Express Setup, or remove the cable boot from the cable in port 1.
Outdoor access points are supported only when they are in Local mode. QoS policies are not supported for port-channel interfaces, tunnel interfaces, and other logical interfaces. Restrictions for Cisco TrustSec: — Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.
When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. As a workaround, disable the logging discriminator on the device. The switch supports physical ports and Etherchannel ports in access and trunk modes.
