SAMPLE COMMAND OUTPUT

Number of WLANs.................................. 3

WLAN ID  WLAN Profile Name / SSID               Status    Interface Name
-------  -------------------------------------  --------  --------------------
4        OfficeFloor / OfficeFloor              Enabled   officefloor_int
5        OfficeLobby / OfficeLobby              Enabled   officelobby_int
6        LoadingBay / LoadingBay                Enabled   loadingbay_int

SUMMARY

STEPS TO REPRODUCE

• Save the above SAMPLE OUTPUT as cisco_wlc_ssh_show_wlan_sum2.raw
• Try parsing raw data by running:

python development_scripts.py -c tests/cisco_wlc_ssh/show_wlan_sum/cisco_wlc_ssh_show_wlan_sum2.raw

EXPECTED RESULTS

Raw output should be parsed into the below yaml:

---
parsed_sample:
  - wlanid: "4"
    profile: "OfficeFloor"
    ssid: "OfficeFloor"
    status: "Enabled"
    interface: "officefloor_int"
    pmip_mobility: ""
  - wlanid: "5"
    profile: "OfficeLobby"
    ssid: "OfficeLobby"
    status: "Enabled"
    interface: "officelobby_int"
    pmip_mobility: ""
  - wlanid: "6"
    profile: "LoadingBay"
    ssid: "LoadingBay"
    status: "Enabled"
    interface: "loadingbay_int"
    pmip_mobility: ""

PROPOSED FIX

• Update cisco_wlc_ssh_show_wlan_sum.textfsm to make PMIP_MOBILITY optional.
