There are several ways to log into an RCE:
SSH
Get the RCE IP address, then ssh.
ssh root@<ip_address>
or
ssh root@`atca_ip <RCE_ID> --ifname <subnet_interface_name>
Example using default eth0 host network interface, no ifname option required
ssh root@`atca_ip shasta/2/3/2`
Example using eth1.204 host ethernet interface, use ifname option
ssh root@`atca_ip shasta/2/0/0 --ifname eth1.204`
The default username and password are both root.
Serial Console
For DPM RCEs, first ssh to the DTM, then use minicom with the bay and rce number
minicom bay<0-3>.<0|2>
For example:
minicom -w bay0.2
The default username and password are both root.
