Hello,   We are seeing URLs categorization shifts. Why would this happen? The Talo website - https://talosintelligence.com/ - lists the site as Non-governmental Organizations , but ever so often we lose access because the site gets re-categorized as a parked domain. Ultimately the categorization normalizes and we regain access, but not before users complain. We would like to avoid putting in an exception.   Advanced thanks. ... View more

Hello. Any and all help appreciated. Please see the attached diagram.   7ks are at the core. 2ks are at the distribution/agg layer(layer 2 only)   The port-channel comes up and all appears well. However Netapp cannot ping(communicate) with Core-A's IP address(SVI) or the VRRP VIP. It can communicate with Core-B, but not the VIP. This same behavior occurs when the Netapps are directly connected to the cores.   A single connection directly to Core-A works; Core-A's SVI is ping-able, as well as the VIP.   There are other Netapp devices in the environment, wired like the diagram, that work. However, different models and OSs. The device in question is a FAS 8200, OS 9.4 P2.   We've really been through the ringer with this. The latest is that NetApp, on this version of software, no longer supports "Fast-Path." Not sure how this would affect us. But on the production netapp system, Fast-path is not enabled. Thank you     ... View more

Hello,   Replacing a 7K environment with 9k.   The 9k gear was purchased with the NXOS image. It was later decided to go with ACI, so two APICs were purchased. Is the ACI image needed for the 9K gear already on the APIC, or is this a separate license purchase?   The existing environment leverages FEXs, which will be moved over to the 9k leaves. Is a license required for FEX to leaf functionality?   Thank you ... View more

Hello. We are upgrading a 7k environment to 9K -  9504 spines and 93180 leafs, to be exact.   The original plan was to use NXOS, which is what the gear was purchased with. It was later decided to go with ACI, so two APICs were purchased.   The project has been on the shelf for a little while. The APICs are running version 1.4.   1) Is the ACI image needed for the spines and leaves on the APICs, or is that a separate purchase? 2) The current 7k environment also leverages FEXs, which will be used in the new ACI environment. I've read that a license is required to use a FEX with the leaves. Is this true?   Thank you ... View more

Hello, I have some 9504s and 93180s to install. They were ordered with NXOS. They will replace a Nexus 7K-> 5k -> 2K environment i the DC. Later on it was decided that ACI was the way to go, so two APICs were purchased.    - Is the ACI software that needs to be installed on the 9504 and 93180s on the APIC?   - I'm reading in ACI books and hearing in ACI training videos that a license is required to use the 2K FEXs with 93180 leaves, yet I can't find anything online to support this. Is this true?   - Can the 2Ks be dual-homed to leaves(does this even make sense)?   - If a 2K is attached to a leaf and successfully configured(pre cut-over), can it be replaced with a production FEX(cut-over) and be expected to operate normally once code is downloaded?   Looking forward to the replies.   Thank you     ...

Hello,   While troubleshooting issues with Port channels to NetApp filers, we discovered that the standby 6880 in our VSS pair is not forwarding traffic.   The two 6880 switches are linked up to a pair of Nexus core switches, using a port channel running LACP.   Regarding the 6880s, one switch is reported as the master, and the other, secondary. We see no apparent issues, however, there are configured port-channels present on the primary that aren't on the secondary. Otherwise, all interfaces are labeled with the proper chassis and slot IDs.   The Cisco VSS doc says that both VSS devices should pass traffic. Am I missing something here.   Where should we focus to sort this out?   Thank you. ... View more
