Cisco 9500 Switch Ios Download ((FULL))

I'm being tasked with some minor network tasks at my position as a system administrator and am running into something new. We have an existing 9500-48y4c and I was provided a second to extend our ports to 96. I was told I can "stack" them??

EDIT : normally i would just connect a cable to one of the other ports, create vlan and add an IP but in this case with this switch (9500) we're occupying all of the ports for use so thats why i would like to use the Management port.

I was asked to purchase another 9500-40X-A to replace a defective unit which has a broken SFP incrusted forever into one port. The current stack is a pair of 9500-40X-A running SVL and looking to replace the defective unit, the Standby of the SVL. Wondering how to and with minimal impact.

Since you mentioned "The current stack is a pair of 9500-40X-A running SVL and looking to replace the defective unit, the Standby of the SVL" then you would want to skip the step from the document that says "If active switch needs to be replaced, perform a failover to Standby switch and wait for standby to take over active's role. (Skip this step if you are replacing Standby unit)."

No, since you mentioned "The current stack is a pair of 9500-40X-A running SVL and looking to replace the defective unit, the Standby of the SVL", then you would work only with the Standby Switch. However, make sure to check if all devices that connect to the SVL are dual-homed before you power off the Standby Switch.

We have a Cisco 9500-40X switch at a new location (single switch). This is the first time we have ever used this particular model. We seem to be having trouble saving the configuration. Every time we power the switch on, the config is gone. I am used to other Cisco switches where I can use 'wr' to save the configuration locally. Does this command not work on this model?

there might be a setting for switch to ignore start-up configs. so, maybe "wr" works but command was issue to ignore it. Normal boot Settings is Configuration register is 0x102 line in show version. Also, look at show boot or show system boot options

As the title suggests, I find it very hard on how do I solve this problem. As a beginner on this networking world, the current switch that I'm using which is Cat9500 16x, why is it showing switch: instead of the normal. Apparently I don't have IOS image after Factory-Reset my switch.

Because the 9500 does not support "emergency-install" the only way to get the flash back in is to boot the firmware from a USB flash drive. Once the switch has boot up, copy the firmware from the USB flash drive into the switch's flash and perform Install Mode (see attachment).

It sounds like your Cat9500 switch is not recognizing the IOS image after you performed a factory reset. This could be due to a few different reasons, such as the image being corrupted or missing, or the switch not being able to locate it in the correct location.

Obtain a valid IOS image from Cisco's website or through a licensed vendor.

Connect to the switch using a console cable and a terminal emulator program.

Enter privileged EXEC mode by typing "enable" and providing the enable password.

Enter configuration mode by typing "configure terminal".

Use the "boot system" command to specify the location of the IOS image. For example, "boot system flash:cat9k_iosxe.16.12.04.SPA.bin".

Save the configuration by typing "write memory" to ensure that the switch boots up with the specified IOS image.

Once you have completed these steps, you should be able to reload the switch and it should recognize the IOS image and boot up normally. If you continue to experience issues, you may need to consult the Cisco documentation or seek assistance from a networking professional.

Hello

The trunk connection between the two switch are different, the 9k is in a LACP port channel and the 3750x is a single trunk, Also confirm the L3 interface/SVI on both switchs are showing up?

As already pointed out, we need more information to figure out why you can't ping. But to answer your question, 3750 is an old switch that can use both dot1q and isl ( cisco proprierty protocol ), that is why you need to specify which of them to use. 9500 can only do dot1q, so this is on by default when you enable trunk. When using different port types, the important thing is to use same type of sfp. If the port state is up then there should be connectivity. You can use "show cdp neighbor" to see if there is traffic going over the link.

I was choosing a Catalyst 9500 switch C9500-16X/C9500-24Y4C, which is having a switching capacity of 480Gbps and 2 TBPS so lets assume if it is configured in stackwise virtual it provide me 480X2=960 GBPs throughput and for 24 port it will provide 2X2=4Tbps. Please confirm the maths is correct ??

All Catalyst 9K switches support non-blocking architectures. There are only 2 possible exceptions: the 24-port 10Gbps fiber and 24-port mGig modules of the Catalyst 9400. I say "possible" because it depends on which Supervisor is used, which chassis is used and the total bandwidth of the connections on the modules. For example, if all of the ports are connected at 1Gbps, then they are all line rate since the total speed would be 24Gbps and the modules can support 80Gbps per slot at a minimum (again, this number can be higher depending on which Supervisor is used and which chassis is used) . Future Catalyst 9400 supervisors will remove this over-subscription, and these modules will then also be non-blocking regardless of connection speed.

The math you have done is correct, but remember that 480Gbps and 2Tbps are the total per switch counting both directions (what I call the "marketing" number). When you create a SWV pair, then you would double the number as you have done. But again, these are counting both directions. For what I call the "engineering" number, take half. Regardless, both of these switches are non-blocking architectures.

As what I was thinking that a switch port which is of 1 gig can handle traffic upto 1 gig , but as u mentioned that are the switches that are in blocking state ??? can you please reply with models that doesn't support with full line rate.

You need soft higher than 16.9.1. In that the virtual-stack for my switches was implemented in a hidden manner. vStack is not automatic and you must be ready to restart. You need at least 2 to 3 cables (it makes sense). Two on the port-channel and one on the keeper. For my hardware, they must be lower ports than Hun1/ 0/16.

I connected a computer with a 25G interface in Cisco Catalyst 9500-48Y4C switch. I saw ports on both PC and the switch are UP (green light). However, the switch could not learn the computer's MAC address. Also, the computer did not know the MAC address of the connected switch port. It seems to be a layer-2 problem. When I tried the ping from the computer to the switch port, as the MAC address of the switch port is not listed on the computer, the broadcast messages were sent out. But what surprised me is that switch still received the broadcast messages from the computer. What is the problem here?

@Leo Laohoo Loop test for switch ports (one cable connecting directly 2 switch ports) and for the computers' interfaces (one cable directly connecting two PCs with 10Gbps NIC) is working well. The status is up/up for both cases.

@balaji.bandi This is Intel NIC spec: -82599es-10-gigabit-ethernet-controller/specifications.html?wapkw=Intel%20Corporation%2082599ES%2010-Gigabit

Two PCs could ping each other using the same cable (directly without the switch in between). Therefore, I do not think it is the NIC issue.

Since it says I can do this prior to the upgrade I can just walk up to the switches and run each command and I will be moved from the 17.3.2r bootloader to 17.6.1r just like that and ready to perform the IOS upgrade?

I can't test this before hand because this is specific to our C9500 X16 switches and I don't have a test so some clarification would be nice before I install the IOS upgrade and hope it boots correctly.

On the C9500-12Q, C9500-16X, C9500-24Q, C9500-40X models of the series, you must manually

upgrade the ROMMON in the primary SPI flash device, if a new version is applicable, and the release

you are upgrading from is Cisco IOS XE Gibraltar 16.12.1 or a later release. (So if you upgrade from

Cisco IOS XE Gibraltar 16.11.1 for example, a manual upgrade does not apply; the ROMMON is

automatically updated, if applicable). Enter theupgrade rom-monitor capsuleprimary switchcommand

in privileged EXEC mode.

There are two ROMMONs. The Primary and the Golden (capsule). The Golden is a backup of the Primary. If the Primary is corrupt, the Golden capsule might take over. However, if both the Primary and Golden is corrupted, the switch is dead.

At the end of the day, you are the owner and operator of that switch. If you see the need to upgrade the Golden (capsule) image, then go for it. I have already expressed my opinion and I do not see the need to always defend it.

I am planning to replace our core switches 3750 with Cat 9500. The plan is slowly migrating the router over to the new core switches because there is production line running on the 3750. Do I need to create add a another subnet in the firewall to carry the traffic out? Could you please help with what would be the best practices and steps to migrate the routing over without disruptions? e24fc04721
