2019年5月18日 · My general rule is to assign subnets to each group as defined by an SGT, as these are the distinct groups of users / devices that usually have policy rules enforced between them. While SGTs are IP agnostic (and IP version agnostic), in my view it makes sense to have a unique subnet per SGT for simplicity sake.

2023年10月14日 · According to the SDA design guide: Reduce subnets and simplify DHCP management —In the overlay, IP subnets can be stretched across the fabric without flooding issues that can happen on large Layer 2 networks. Use fewer subnets and DHCP scopes for

2019年9月11日 · I believe Cisco is working on allowing engineers to create their own "closed auth" template that you can use to provision all nodes. Do you split the ports between these VLANs/subnets ? or use a default VLAN/subnet, and then let …

2022年3月19日 · 1 SDA核心-通过一系列的技术合租,组织到一个平面上 载体:DNA Center 在华为的载体是AC Agile Contro (不是无线AP哈!) 对比传统 传统三层网络 1.要备份,设备多,容易配置错,而且出问题了不好排错 SD-Access 1.可以部署自动化下发配置 2.支持PNP (即插即用)plug and play

2020年12月3日 · Do you have 3 buildings, each with their own /24 data subnet? Cool, in SDA you'll probably create a Campus VN with a /22 data IP pool instead and share it across all buildings. Start with standing up the DNAC cluster, and get border nodes that are not part of your legacy environment.

Wired Intra-Subnet Traffic Flow. Lets suppose source and destination on same subnet and want to communicates to each other. The source endpoint (A) sends an ARP request for the MAC address of the destination endpoint (B).

2025年1月13日 · Instead of creating a subnet, IP address range is blocked for both DHCP pool allocation and IP address assignment for point-to-point links, loopback, and multicast. The LAN automation workflow supports assignment of IP address pools with /27, /28, and /29 subnet masks. IP Pool Usage Example

2023年8月30日 · I have 2x office sites and my plan is to create a fabric in each site and orchestrated by DNAC located at my DC. My questions are, 1. Similar to ACI, can stretch my VN from site 1 to site 2 with one subnet across two sites? If it is possible, will this be the best practice for SDA or I should just have different subnet for each fabric? 2.
