1 Introduction

This document describes how to view supported Secure Shell (SSH) algorithms.

1.1 Prerequisites

This section describes the prerequisites, which must be fulfilled before using the procedure.

1.1.1 Conditions

The following conditions must apply:

The user has the System Security Administrator role.
An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

2 SSH Algorithm Format

The value of attribute selectedCiphers consists of a string list of ciphers that must include at least one string. Each algorithm in the list must be in the supportedCiphers list.

The value of attribute selectedKeyExchanges consists of a string list of key exchanges that must include at least one string. Each algorithm in the list must be in the supportedKeyExchanges list.

The value of attribute selectedMacs consists of a string list of message authentication codes that must include at least one string. Each algorithm in the list must be in the supportedMacs list.

To view the SSH algorithm format:

Verify the SSH algorithm format:

(Ssh=1)>show -v

The following is an example output:
