And how this scenario was implemented? Did you use dynamic routing (ospf, eigrp etc) or not? If i understood correctly, you configured port from a switchs side as l3 port (no switchport).

Hello Balaji. Thanks for answer. But according to this link, there is no version 17.3.x for the specified series. https://www.cisco.com/c/en/us/support/switches/catalyst-9500-series-switches/products-installation-and-configuration-guides-list.html And with what model were these problems with the module GLC-T? Did you use C9500-48Y4C or C9500-40X?

Hello everybody. Does anyone have experience using catalyst 9500 switch as a core in VSS? We want to use C9500-48Y4C model, because it supports the features we require - vss and different type of sfp modules (glc-t/te, glc-lh-smd). As i know, vss for C9500-48Y4C supported starting from version 16.10.1.

He for everybody. I download and install key for activating 3des-aes feature for asa 5508-x. It turned out that this license is temporary, for 28 days only. Validating activation key. This may take a few minutes... The requested key is a timebased key and is activated, it has 28 days remaining. ... Encryption-DES : Enabled perpetual Encryption-3DES-AES : Enabled 28 days ... Is it possible to fix and and make this 28 days perpetual, maybe i need to buy any license?

Hello. What is difference between CON-SNT-A15K9 and CON-SNT-A15K8. This is contract for cisco asa 5515-x. If i understood correctly, K9 means that the device supports encryption aes/3des. And K8 - only des encryption. And if i can see smth like this Encryption-DES : Enabled perpetual Encryption-3DES-AES : Enabled perpetual I need CON-SNT-A15K9.

Hi. Thanks for answer. Right now we have one 4331 as "router on a stick" and old 3750 with 12 sfp. And we are thinking of reserving it with the second 4331. If i understood correctly, in the second router we need to create a subinterface in the same as the first 4331 vlan + vrrp subinterface. But there is a problem - this router is the owner of DHCP pools (i know that it is wrong, but it is impossible to change it at this time).
