Current Release: Prior Releases: With previous software releases, you cannot upgrade the ROMMON without bringing down both supervisor engines simultaneously.
SG or later. Supports the Preboot Execution Environment PXE feature, also called PXE boot—A network boot loader that enables the switch to retrieve the software image and other files from a remote server, during the initial deployment, without requiring end-user intervention Zero-Touch Provisioning. You can specify a remote TFTP server to download the software image and other files.
This is also the recommended setting if you are using an existing device and upgrading to this version. Workaround: Power off and then power on the devices. If required, perform a reset instead. Workaround: Upgrade the ROMMON version on both supervisor engines simultaneously, to ensure that the uplinks are down when during the upgrade.
Workaround: Connect system console to a device that saves the output. This document describes the procedure for a single supervisor system. You must perform the process on each supervisor in a dual supervisor system. Step 1 Directly connect a serial cable to the console port of the supervisor engine. Note This section assumes that the console baud rate is set to default.
If you want to use a different baud rate, change the configuration register value for your switch. Step 3 Use the dir bootflash: command to ensure that sufficient space exists in Flash memory to store the PROM upgrade image. If you are using an SD card, replace bootflash: with slot Note On a redundant system, this action causes a switchover.
The following example shows the output from a successful upgrade, followed by a system reset:. This may happen automatically if the system is configured to auto-boot. Step 9 On a redundant system, hook up a console to the now-active supervisor engine. After the system achieves an SSO state, repeat steps Step 11 Use the delete command on the active supervisor to delete the PROM upgrade program from bootflash. Step 12 On a redundant system, also delete the upgrade file from the standby supervisor engine.
This procedure can be used when console access is not available and when the ROMMON upgrade must be performed remotely. Step 1 Establish a Telnet session to the supervisor engine. Note In the following discussion, we assume that at least one IP address has been assigned to either an SVI or a routed port.
Step 2 Download the bootflash:cate-ios-promupgrader-SG2 program from Cisco. The bootflash:cate-ios-promupgrader-SG2 programs are available on Cisco. Step 3 Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the PROM upgrade image. If there is insufficient space, delete one or more images. Step 4 Download the bootflash:cate-ios-promupgrader-SG2 program into Flash memory using the copy tftp command.
The following example shows how to download the PROM upgrade image bootflash:cate-ios-promupgrader-SG2 from the remote host In this example, the BOOT variable was set to boot the image cate-universal. Step 6 Use the show bootvar command to verify the boot string. Cisco IOS Flexible NetFlow is the next generation in flow technology, allowing optimization of the network infrastructure, reducing operation costs, and improving capacity planning and security incident detection with increased flexibility and scalability.
The flow data collected by FNF can be exported to an external collector for analysis and reporting, or tracked by the EEM.
The Cisco Catalyst E Supervisor Engine 7-E enables powerful, on-box, and customizable event correlation and policy actions with EEM, allowing the switches to trigger customized event alarms or policy actions when the predefined condition is met. With no external appliance required, customers are able to use existing infrastructure to perform traffic monitoring, making traffic analysis economical even on a large IP network. Already-installed Cisco Catalyst E chassis with classic and E-Series line cards can take advantage of the new features and functions of the Supervisor Engine 7-E on all ports with a simple supervisor-engine upgrade.
You can mix and match Cisco Catalyst E Series line cards and classic line cards in an E-Series chassis with no performance degradation to either line-card type. Table 2 shows the supervisor-engine and line-card slot-assignment options in the Cisco Catalyst E Series chassis. Table 2. Classic Line-Card Slot Options. Cisco Catalyst E. Slot 1. Slots 2 and 3.
Slots 2 through 6. Slot 3 or 4. Slots 3 or 4. Slots 1, 2, and 5 to 7. Slots 5 or 6. Slots 1 to 4, and 7 to Cisco Catalyst R-E. Table 3 summarizes the performance capacities of the Supervisor Engine 7-E on a per-chassis basis. Table 3. Cisco Catalyst E Chassis. Cisco Catalyst R-E Chassis.
IPv6 is important for the future of IP networking and is critical for the expansion of IP address space in the future. IPv6 capability is required by many companies and is being mandated by governments worldwide. Table 4. IPv6 support. Unicast and Multicast forwarding done in hardware. IPv6 performance. IPv6 Routing entries. Dynamic Hardware Route Table allocations. Yes, in hardware. Enterprise networks use single foundational infrastructure to build multiple logical overlay networks for diversified closed usergroups, regulatory, secure IT applications, etc.
On campuses the traditional Multi-VRF solution is widely adopted and deployed to solve such network segmentation challenges. The data-plane security and protection are maintained through industry-standard IEEE It includes all Layer 2 features and some basic Layer 3 features. These features can be enabled using the software-licensing mechanism.
The minimum software version is as follows:. This result is not indicative of the actual power draw during operation. It is the absolute maximum value recommended for facility power and cooling capacity planning. Typical power draw is about 20 percent lower than the maximum value shown.
