Python Pexpect - SSH Timeout

[Nirmal]

Got to know its getting failed here...

def macGrabber(child,switch,cat = False):
    try:
        if cat is False:
            child.expect('.#')
            child.sendline('sh mac address-table | no-more')
        else:
            child.sendline('sh mac address-table dynamic | i Gi')
        child.expect('.#', timeout=3000)
    except pexpect.TIMEOUT:
        print child.before,child.after
        child.close()
        raise
    macs = child.before
    child.close()
    macs = macs.splitlines()
    print('Connection to %s CLOSED' % switch)
    return macs

Can we set a retry here ?
