I am having issues with securing the Dell N-Series switches we have on-site.  Security is telling me we are getting the above error on the vulnerability scans.

I have the following configured

no ip http secure-protocol TLS1.0 TLS 1.1

ip http secure-ciphersuite ecdhe-rsa-aes-gcm-sha2 rsa-aes-cbc-sha2

We are still seeing issues with

• Insecure MAC algorithms in use: hmac-sha1,hmac-sha1-etm@openssh.com,hmac-md5-etm@openssh.com,hmac-sha1-96-etm@openssh.com,hmac-md5-96-etm@openssh.com,hmac-md5

How can I resolved this issue?
